Kitchen drawer and hardware 12

  • A bicycle with two jar lids for wheels and a frame of nails laid flat Lay it out dry on card and photograph it before gluing. The lids stay bare metal. White glue.
  • A clock that tells no time: springs, cogs and hinges inside a cake tin lid Arrange from the center outward like real clockwork, then stop early. Empty tin is part of it. Tacky glue.
  • A dragonfly with a long bolt for a body and two pairs of wing nuts The wing nuts are the wings; nothing else is needed. Bind them to the bolt with fine wire.
  • A fish whose scales are metal washers overlapped along a painted board Washers in three sizes. Start at the tail and overlap toward the head so they read as scales. White glue.
  • A robot face from a jar lid, two bolts and a row of old keys for teeth Keep to silver finds only, so it reads as one machine. An adult hot-glues the metal down.
  • A side-view face from nuts and hooks with one cup hook for the ear Draw the profile in pencil first. Crowd the finds along the line and thin them out toward the back. White glue.
  • A skyline of keys standing head-down along a strip of wood Sort the keys by height first and put the tallest off-center. Press them into a line of tacky glue.
  • A sun made of a jar lid ringed with wooden clothespins Clip the pins round the rim, then paint only every second one. No glue at all.
  • A vase of flowers whose blooms are old spoons fanned in circles Five or six spoons to a bloom, bowls outward. One bloom in forks breaks the pattern. An adult hot-glues.
  • An owl with two tea strainers for eyes and teaspoons for wings Leave the strainers unpainted; the mesh is the stare. Thread thin wire through the handles to hang them.
  • Six insects in rows, each built from a different hinge, hook or drawer pull Give every insect the same paper-clip legs so the set holds together. Label each in pencil. Tacky glue.
  • Your initial packed solid with silver finds from the drawer and nothing of another color One color is the rule: if it is not silver, it goes back. Pack the pieces tight inside a pencil outline.

Wood offcuts and driftwood 12

  • A bird on a perch from a wedge body, a sliver beak and two wire legs Tilt the wedge forward as if it is about to hop. Push the wire legs into a clay base.
  • A city seen from above: offcut ends packed on a board and painted one white Different heights, one color: the shadows do the drawing. Pack them tight like a street map. Wood glue.
  • A forest of twig trees standing in modeling clay along a plank Vary the heights and lean two toward each other. Leave the twigs bare. Clay holds them; no glue.
  • A four-legged creature from one forked stick, whatever the stick suggests Turn the stick until you see an animal, then add only eyes and a tail. Bind the extras on with twine.
  • A long fish from one driftwood piece with offcut fins and a knothole eye Choose the stick for its eye first; everything else follows. Fins go on with wood glue and a day to set.
  • A plank face with offcut eyebrows, a dowel nose and a curved twig mouth Move the eyebrows before you glue: a small tilt changes the mood. Wood glue.
  • A row of crooked houses from offcuts of different heights Paint the roofs and leave the walls raw. Stand them close so the gaps become alleys. White glue to a plank.
  • A sunburst of craft sticks and wood chips spreading from a round offcut Long sticks first like clock hands, chips in the gaps. Paint the round center only. White glue.
  • A tower of offcuts glued slightly off-center so it seems to lean Biggest block at the bottom, each one shifted the same way. Stop while it still stands. Wood glue.
  • A village on a shelf: each offcut a building with windows in pencil only No paint. Draw doors and windows lightly and let the grain be the walls. Nothing is joined, so it can be rearranged.
  • A whale from a slab of bark with a spout of curled wood shavings Rough side out for the skin. One white dot of paint for the eye. Tacky glue holds the shavings.
  • A wind-bent tree with a curved driftwood trunk and offcut-chip leaves all blown one way Glue every chip pointing the same way, as if in a gale. The trunk stays bare. Wood glue on a plank.

Toys and plastic 12

  • A checkered floor of dominoes and game counters leading to a tiny paper door Alternate dark and light pieces in strict rows. The door at the far edge makes it a room. White glue.
  • A color-wheel clock: twelve small toys, each a different hue, round a paper plate Red at twelve, then round in rainbow order. Trade toys until no two neighbors match. Tacky glue.
  • A creature with a toy-car body, doll arms and plastic-fork antlers Use parts from at least three toys so no one toy can be named. An adult hot-glues the joints.
  • A face in profile filled with small plastic toys, hair one color and skin another Two colors only. Draw the outline large, fill the hair first, then the face. Tacky glue.
  • A monster whose many eyes are wheels taken from broken toy cars Stuff a sock for the body and cover its front with wheels of all sizes. An adult hot-glues them on.
  • A parade of plastic animals crossing a bridge of rulers Largest animal first, smallest last. Two rulers on block piers make the bridge. Poster putty, so it can change.
  • A portrait of a pet from jigsaw pieces sorted from light to dark Turn every piece face down and sort by the gray of its back. Dark pieces for ears and eyes. White glue.
  • A rainbow sorted from a tub of mixed toy parts, one arc for each color Sort into bowls before anything else. Pack each arc tight and let odd shapes stick out. White glue on card.
  • A robot dog with a toy-truck body, marker-cap legs and a spring tail Keep the truck's wheels on: they are the dog's shoulders. An adult hot-glues the caps underneath.
  • A wreath of plastic animals painted one flat white Glue the animals nose to tail round a card ring, then brush white over all of it so the shapes take over.
  • An aquarium in a clear food tub with thread-hung plastic fish and bead gravel Hang the fish at three depths so they overlap when seen from the side. Tape the threads under the lid.
  • Flowers with plastic-spoon petals round a jar-lid center Eight white spoons to a flower, bowls up. Paint the lid, not the spoons. Tacky glue on a board.

Packaging and recycling 18

  • A coral reef in a shoebox lid from straws, net bags and scrunched wrappers Stand the straws up in clay, drape the net over them and tuck wrappers into the gaps.
  • A dragon's spine of egg-carton peaks marching along a row of tubes Paint the peaks and leave the tubes gray. Tape the tubes end to end so the body can bend.
  • A giant letter covered in packaging of a single color Cut the letter from a box. Collect only red packaging, or only blue, and overlap it. Glue stick.
  • A jellyfish from a clear plastic tub trailing strips of shopping bag Turn the tub upside down and tape the strips inside the rim. Hang it by a thread through the base.
  • A koi of jar lids and bottle tops, warm colors on its back and white on its belly Collect for a week and sort by color. Biggest lids in the middle of the body. Tacky glue on cardboard.
  • A night city of small boxes painted black with yellow sticker-dot windows Stand the boxes at different angles. Put lights on in only some windows. Nothing is glued.
  • A paper-bag owl stuffed with newspaper, with two foil lids for eyes Twist the top corners into ears and tie the bag at the bottom. Draw the feathers on in marker.
  • A portrait made from bread tags and twist ties Tags for skin and teeth, twisted ties for hair. Sort the tags by color before you start. White glue.
  • A rocket from a chip tube with a paper-cup nose and tape stripes Three card fins slot into cuts at the base, made by an adult. Wrap bright tape for the stripes.
  • A shiny mosaic sun from the silver insides of chip bags Wash the bags, cut squares and lay them silver side up in rings. Leave a thin gap between pieces. Glue stick.
  • A snack machine from a cereal box, with rolled-wrapper snacks on shelves behind a clear window Roll wrapper scraps into tiny packets on card shelves. An adult cuts the window; tape clear wrap behind it.
  • A standing robot from a cereal box, two tubes and four lids, every label showing Do not paint it: the printed labels are its skin. Slot the tube arms through holes an adult cuts.
  • A striped beacon tower of yogurt cups stacked rim to rim in the colors they came in Stack them rim to rim and base to base. Do not paint; the stripes are already there. Tape inside.
  • A tortoise whose shell is a paper bowl covered in overlapping lid scales Head and legs are five corks or tube ends. Start the scales at the rim and work up. Tacky glue.
  • A wall clock face with every numeral cut from a different box Hunt the twelve numbers on packaging first. Arrange them round a plate before gluing. Glue stick.
  • A weaving of plastic-bag strips through a net fruit bag Stretch the net over a card frame. Weave over and under in bands of color. No glue, only knots.
  • An invented island as a relief map of scrunched foil and bottle tops Foil for mountains, tops for towns, blue bag for sea. Decide the coastline first. White glue.
  • Flowers of flattened paper cups round bottle-top centers Snip each cup's wall into petals and press it flat. Three cup sizes make three kinds of flower. Tacky glue.

Boxes and shadow boxes 12

  • A beach shadow box with glued sand, shells and a strip of blue paper sea Sea at the back, sand at the front, shells largest first. Brush white glue on, then pour the sand.
  • A chest of six empty matchboxes, each drawer holding one small found thing Glue the sleeves in two stacks of three. Bead handles on paper fasteners. One find to a drawer.
  • A divided box with one color to each compartment, filled with small finds Use a box that already has dividers. Fill by color only, whatever the things are. Nothing glued.
  • A matchbox aquarium with paper fish on threads behind a cellophane window An adult cuts the window in the sleeve. Tape threads to the tray's roof so the fish swing.
  • A matchbox garden of green felt with a bead flower and a paper bee Line the tray with felt. The bee flies on a thread glued to the inside of the sleeve.
  • A matchbox theater: the tray is the stage and the sleeve its curtain Stand the tray on end. Paper actors on strips slide in from the side. Paint the sleeve red.
  • A memory box for one person: a button, a ticket, a key and a photo corner Choose four things, not forty. Back the box with a page from an old map or letter. Tacky glue.
  • A painted matchbox sleeve that turns the empty box into a little book Paint a spine on one long side and page lines on the others. The tray becomes its secret drawer.
  • A shadow box of one day's pocket finds, labeled like museum specimens Pin each find in its own space and write a tiny label under it. Even gaps make it look serious.
  • A shoebox room seen through a peephole and lit by a tissue-paper skylight An adult cuts the peephole and the skylight. Furniture is folded card. The lid stays on.
  • A tiny bedroom in an empty matchbox tray with a postage-stamp picture on its wall Bed from a folded scrap of cloth, rug from a label. Everything must fit so the sleeve still shuts. White glue.
  • An empty matchbox that slides open to show a folded paper message Fold the note like a fan so it springs up when the tray opens. Decorate the sleeve to hint at it.

Altered objects 12

  • A book folded page by page until its edge fans into a hedgehog No cutting: fold every page corner to the spine. Add a paper nose and eyes to the cover.
  • A drawer stood on end as a cabinet of curiosities with three card shelves Slot the shelves in tight so no glue is needed. One find to a shelf, with a handwritten label.
  • A frame whose border is covered edge to edge in one kind of thing Pencils, shells or dried pasta: pick one and repeat it. The empty middle becomes the picture. Tacky glue.
  • A glove that becomes a family of five, one face to a finger Stuff the fingers with paper. Button eyes and yarn hair, sewn or tacky-glued. Each face a different mood.
  • A hardback cover opened flat as a stage with pop-up scenery at the hinge Remove the pages first. Fold scenery so it stands when the cover opens to a right angle. Glue stick.
  • A hinged tin turned into a pocket landscape with a paper horizon Sky inside the lid, land inside the base. One tiny figure gives it scale. Glue stick.
  • A silverware tray stood upright as an apartment block with a scene in every slot Each slot is one home: wallpaper it with a different scrap. Card furniture, glue stick.
  • A stopped clock whose face becomes a small stage for paper figures Leave the numerals showing behind the figures. Stand them on folded tabs. Glue stick.
  • A teacup holding a paper sea with a walnut-shell boat Cut waves from blue magazine pages and layer them to the rim. The boat sits on top, unglued.
  • A worn-out shoe turned into a house for an invented creature Paint a door at the heel and windows along the side. Laces become a ladder. Acrylic paint, no glue.
  • An empty picture frame strung with wire and hung with keys and charms Wind three wires across the back. Hang the heaviest thing lowest. The gaps matter as much as the finds.
  • An old book with a window through its pages that frames a small toy An adult cuts the window with a craft knife. Glue the cut pages into a block and seat the toy inside.

Cardboard 12

  • A cardboard portrait with the top paper peeled back so the ridges become hair Dampen the top layer and peel it away above the forehead. Leave the face smooth.
  • A cardboard relief pangolin armored with rows of overlapping card triangles Start the rows at the tail. Peel some triangles to the ridges and leave others smooth. White glue.
  • A cityscape of cardboard strips stood on edge, tallest at the back The corrugated edge faces forward as rows of windows. Glue the strips to a base in three ranks.
  • A corrugated cardboard tiger with every second stripe peeled down to the ridges Draw the stripes, score along them and peel every second one. An adult does the scoring.
  • A flat-pack cardboard animal of two side profiles and three cross pieces pushed into slots Cut slots half the depth of each piece and push them together. No glue, so it packs flat again.
  • A moth drawn in white paint on brown cardboard, the board left as the mid-tone White for light, black pen for dark, bare card for everything between. Dab the wing dust with a sponge.
  • A slotted tree from two matching cardboard profiles crossed at the trunk One slot from the top down, one from the bottom up. Paint nothing; the brown is the bark.
  • A still life painted thinly on a flattened box so the printed labels show through Thin poster paint with water. Let a barcode or a line of small print sit inside the fruit bowl.
  • A sunset in three bands of poster paint dragged across corrugated cardboard Peel the top layer first. Drag a dry brush across the ridges so the color catches only the peaks.
  • A tower built from notched cardboard squares that comes apart again Cut four notches in each square. Build outward as well as up. No glue, so it can be rebuilt.
  • An owl in black pen and white chalk on the flap of a brown box Use the fold of the flap as the branch. Chalk the chest feathers and ink the eyes last.
  • Seven cardboard contours stacked into a relief of hills like a map Cut each layer a little smaller than the last. Space them with card scraps so shadows show. White glue.

How it works

Assemblage is collage in three dimensions: found objects joined into a picture or a figure. These 90 assemblage art ideas are sorted by what you gather. Hot glue and craft knives are an adult's job.

Trash art ideas from the recycling bin

Packaging and recycling holds recycled assemblage art ideas made from lids, boxes, tubes and bags: a koi of jar lids and bottle tops, a night city of small black boxes. Many carry the Easy mark.

Box art ideas, from a matchbox to a drawer

In Boxes and shadow boxes, seven start from an empty matchbox: a tiny bedroom in the tray, a message that slides out, a theater with the sleeve as its curtain. The others fill a shadow box, a shoebox or a divided box.

  • Hot glue guns and craft knives are an adult's job. No project marked Easy needs either.

Questions and answers

What is assemblage art, and how is it different from collage?

Assemblage is made of three-dimensional pieces, usually found objects, that project from a base or stand free. Collage is the two-dimensional version, in paper. A fish of metal washers is assemblage; a fish cut from magazines is collage.

What are some shadow box art ideas?

Four here: one day's pocket finds labeled like museum specimens, a beach with glued sand and shells, a memory box for one person, and a shoebox room seen through a peephole.

Are there matchbox art ideas?

Seven, each from an empty box: a tiny bedroom, a sliding message, a sleeve painted as a little book, an aquarium, a chest of six drawers, a theater and a felt garden.

What are altered art ideas?

An altered object keeps its shape and changes its job. Altered objects holds 12: a book folded into a hedgehog, a hinged tin as a pocket landscape, a silverware tray stood up as an apartment block.

Which are the cardboard art ideas?

Cardboard holds 12: stacked contour hills, slotted animals that stand with no glue, a portrait peeled back to the ridges. Four are cardboard painting ideas, painted or drawn on brown card, such as a moth in white paint.
