Thank you for having the DJ challenge again. I've always wanted to make one. These blocks are so addictive, I'm loving it!! The only problem I'm having is the 1/4" seam. I have a Viking Designer 1, can select 1/4" but it seems to be a little more generous, blocks are ending up about 1/8" short. This never seemed to be a problem when making all the other quilts that I have done. So I had to redo a couple after adjusting my seam allowance. I'm loving the PP blocks and am jumping ahead and doing some of the easy appliqued blocks. I'll send some pictures when I learn how to load them to my laptop.
