How it works
A glass block is hollow and lets light through while blurring what is behind it. These 60 designs use its square front face, its back face and, for some, light from behind or inside.

Two faces, one picture
The block has a front and a back with a gap between, so eleven designs set one layer behind another: Black pines on the front face, gray pines on the back face is planned as a far row behind a near one. How clearly the back layer shows depends on how see-through your block is. The silhouettes are solid shapes planned to block the light: Solid black face with one clear initial of your own.
Christmas painted glass block ideas
Twelve designs are for December, all without a word unless you add your own: Fir tree of stacked green strokes, widest at the foot leaves gaps for the light, and Reindeer head-on, antlers reaching the two top corners fills the whole square.
Questions and answers
What paint do you use on a glass block?
We do not test paints. Whether a paint grips glass, needs curing or stays see-through is on its label, so read it before you buy.
Do the designs need lights inside the block?
No. None of the 60 needs a light: each is a picture on the glass. The twelve silhouettes and the designs with a part left clear, such as Log cabin with its one window left clear for the light, are planned for a lit block.
Which glass block designs are for fall and Halloween?
Twelve, among them Pumpkin patch on the front face, a huge moon on the back, Pair of eyes left clear in a solid black face and Leaf shapes left clear in a sponged rust face. None of them is frightening.
Can I paint more than one block as a set?
Yes. Row of three blocks, one frosted capital of your own on each spells a short word across three, and Two blocks as bookends, half a globe on each splits one picture over a pair.
