I know someone said it already but don't beat yourself up. It's all part of the process especially if it is going to cause problems as you continue. Sometimes I rip because I know it isn't going to be as I imagined it if I continue with it as is. When I started quilting, I invested in a new seam ripper with a cushioned grip when JAF had a 60 percent off their notions wall. The next year I bought a second one when the sale came along again so I could keep one by the machine and one where I did handwork.
