Yes, I would guess all crafters feel the way you are feeling right now more often than we'd like to. I feel that way every time I start a new project, then I fiddle with it. Get the hang of it a bit better ...and then make more mistakes.... I usually tell myself after the project is finished and quilted all the imperfections fade out. Then I think of those quilters who intentionally put a mistake in each project just so they can remember they are not perfect!! Well, no need for that here! Piecing may not be your strongest suit, mine either. But I am better at other things.
