My page has a cross stitch (and other stuff) sampler. When I look at the picture of it, I realize....I'm NOT a very good seamstress. The sampler really isn't straight on the page- so I pinned a bow in the corner to try to distract from it.
My mother is an excellent seamtress and master quilt maker- everything she makes has perfect seams and meets up exactly. She says if she has a mistake it bothers her until she fixes it. She has some early projects with tiny imperfections that she didn't fix and whenever she looks at them, all she sees is the mistake. She calls them "bothermes".
So the rule she follows is "If it bothers me now, it will bother me later". I also subscribe to this rule- but not nearly as much bothers me as bothers my Mom.
Not perfect, but it doesn't have any "bothersme".
