My husband cut the wood tiles, I covered them in fabric. We put in several surprises to pull people in. Polymer clay, jewelry, beads, stones, metal bits, a plastic hand. He then built the frame for it. It looks like a traditional Jacob's Ladder quilt, but there is absolutely no sewing involved, I found a way to combine my love of fabric and mosaic.
The squares are 1" and the triangles are 2" 1/2 sq. triangles. : )
