Yes 1931. They had the basic quilt designs already 'drawn' out for us. "They" being Ruby Short McKim and others. Have you heard of her? There is a new to me site listing all the blocks that she published in the 1930's.
101 Blocks to be exact. As I started browsing them, I thought of all of you in blog land. Have you seen her designs and so forth.
I find them fascinatingly similar to the designs we see today.
The way she uses a solid for the "peel" of a Lafayette Orange Peel .
