Thanks for the nice comments.
I found the pattern online. Easy-peasy. Basically 3 x 3 inch squares with 5 1/2 x 3 inch rectangles all over.
I used my own fabrics (Kaffe Fasset charm packs and various coloured polka dots from the LQS.) I bought the pattern, not the kit. I have seen it in quilt magazines and books, in Civil War, black backgrounds with brights, pastels, and red, white and blue. etc. So, I'm not sure they are the only source of the pattern. We did it as a mystery quilt in our guild this year, and since I was in charge, I had to finish is quickly! If you want the name of the shop, just email me, and I'd be happy to sen it to you.
