As accurate as I can be, especially making sure points aren't cut off. Cutting on the straight of grain - remember making clothing and using the grain arrows on the pattern. Sometimes things aren't perfect, and I'll give myself 2 tries to rip it and/or re-do it. If 2 tries don't result in a better match or getting out a pucker, I move on. I'm not a huge perfectionist, but I want things to look as nice as I can make, especially when sewing for others.
