The boy's drawing came home from school for some more detail work...and he said I could share here. It's kinda quilty, because the birds have feathers :) He said most of his classmates couldn't see the birds, but I sure can. I hope you can too. I bet his friends see the birds now that he's drawn on the feathers.
I think a lot of quilt blocks are tessellations...this drawing reminds me of pinwheel-style blocks.
