I really hated the kitty-cat quilt I made for my niece. It had 72 cat blocks and each of them had triangles for the ears and I discovered I'm terrible at sewing triangles properly, so about 70 of the kitties ended up looking like they'd lost part of their ears in a fight because I lost so many points! I also got sick and I was in a time crunch trying to finish it before Christmas and I kept making really really DUMB mistakes and having to re-do a lot. I was SO GLAD when I put the final stitch into that quilt!!
