I aim for "precision" and it is an ongoing effort. I will never be perfect, don't try, but I like things to at least look good. Since I wash and dry my quilts when they are done, this hides a lot. I"m with you on thinking I cut well and have a quarter inch foot and have learned not to veer off at the end and still sometimes something is a bit off. I don't like the pleats/wrinkles at all, so will fix that, even if tedious. I can usually sew so as not to cut off points.
