I could never get anything done when I tried for perfection. Now I just do it all for fun and pleasure and I have lots of checked off things on my to do list. What I do notice though is that as I keep going my skills are improving. So without stressing I'm actually getting closer and closer to what is considered perfection. =)
And like many others here...I have memories and quilt tops from my grandma..who did NOT do it perfect. I even have some of her cardboard and sandpaper templates. But I treasure her quilts above all.
