Off Topic Side Bar: It requires 36 different fabrics - also insane. The longest bit is 6" and the widest is about 3.5". Most are smaller than that.
But not as small as the 144 1" squares for your pixelated blocks!
After those, 36 sounds like child's play. I'll be happy to send some scraps. As AIMR noted, then we won't have to sort and restore those scraps.
Tiny, but nice straight little squares and not paper piecing odd shapes.
I need to sit down & start sewing! I have cut out the pieces for the Chinese lanterns, maple leaves, garden fences, House That Jack Built, and 2/3 of the whirligigs. And grouped all my icky thump fabrics, printed the template, & given it the evil eye. Alas, nothing to take a picture of, other than my Ziplocks...
