I must be an optimist. I don't even know where a seam ripper is! I know I have a couple but I never use them. I use my thread snippers if I have to take out a seam. I don't unsew the way most people do either. I just cut every 4th to 6th stitch on one side only and then pull the whole thread on the other side. I never rip down thru the middle of the fabrics.
