It depends on how hard the shape has become to be able to adjust it. I usually have to pull off the smaller shapes and re-do them because I'm a perfectionist also, haha! Like today, I was doing Felt Abes face details and I had to re-do it again because it just didn't go right... it still isn't right and doesn't look exactly like Creamface's face which I'm pretty annoyed about but I'm just going to finish it and see how it turns out. I've put the nose too low so you can't see his mouth, but oh well!
Also the plastic eyes I got are too small so I'll have to use wool instead. I can use those for something else
