In my head, I am a perfectionist. In my work, I am not. I will look at things and plan how it should go and can still make silly mistakes. Rip it out and fix it and I will let you compete for my title of the "Unsewing Queen!"
Challenges stretch us and make us grow. You have a beautiful piece of work. I bought the Piecemakers' Bargello book and haven't tried it yet. I want to, though.
