I would be celebrating if I completed a quilt with only one 'oops'. I know me well enough to think I would 'fix it'. However, matching the fix into what is there without it showing would be another challenge. I think I would perhaps move along and see whether or not there are any more 'oops'. Most of us would probably say that most of the quilts we finish have a few imperfections. Mine do but I never point them out.
