Thanks everyone. I have sewn curved blocks before--in fact have a whole quilt with some. I was doing okay until the second round and once I saw I was having trouble I just didn't care if it came out even. So the block is trash. I figure if I'm not enjoying the ride then pass the block. This is my quilt, not the book's. At the same time, my humble homage goes out to those who mastered the piecing.
