I realized I forgot to tell what "mistake" I had made with my last "Tweets" block.
The feathers on the right bird are under the wing, not under the body. And the middle feather should probably sit on top of the light blue ones even though they are underneath in the pattern. Arggghhh.
The good news is that I'm terrible at fusible webbing and the pieces are falling off so I'll be able to fix the block.
