Thanks for the link to the site.
Did you see that the quilter/author made over 1000 blocks (making numerous Crumb quilts).
On the right hand side of her blog click on Crumb blocks to read all her posts about the blocks.
This does look like fun. It also looks like it could be 'an organized scrappy' quilt...something I like better than just 'scrappy'. May try it in June at a machine that sitting all alone and not used.
