sometimes I put it away for a while like a month or two or if the mistake is not too bad...like points not matching completely or other alignment problem....I live with it....quilting for me is a hobby...I do not sell my stuff and I like designing and working with colors more than actually piecing and quilting so even though I am hard on myself, I am not a true perfectionist, and can live with the fact that everything does not turn out the way I intended. I always finish and if not to my liking my dog, Todie, does not care. He loves a new warm bed...lol.
