That’s how many seams I had to un-sew. I was blithely sewing along on the Double 4-Patch and stitched up a stack of 50 blocks. When I started to press them I realized that I had sewn ten correctly like in the first photo. But then I must have flipped the block when I put it under the needle because the other 40 were stitched like this one:
Not exactly the look I was going for *sigh*.
I am sewing up over 200 of these blocks, which is actually more than I need but I want enough blocks to be able to swap out if I want.
