I had fun piecing this, thanks to Mary's vellum, Tara's cutting map and Jackie's excellent tutorial!
Still, it seems like it came out a little lop-sided. I may have cut one of the square blocks on the wrong line?? I've tried and tried to figure it out with no success. I ended up re-sewing the 4 blocks together in a different way. I'll go ahead and send it. Mary, maybe you can figure out where I went wrong. If you send more fabric and vellums, I'll be happy to do it over again!
