There will be projects like that! But why? Do we really need to prove our perseverance? I do sympathize. Been there, done that. Haven't we all?
Your quilt looks lovely from here. I see not a thing wrong with it!
Love the lump!!! That kitty knew you needed a smile and was just there to lend his support the best way he knew.
On with the next project. You've had all the errors possible in this project so you won't have to worry about them occurring again anytime soon.
