My quilts are far from perfect, but they are charming!
I agree with Prism about hand made quilts needing to have that human quality. I do sell some quilts on occasion... but they are not perfect. The people who buy quilts usually don't see our imperfections, they just see a cozy quilt and fall in love with it. I don't think you need to go for perfection in your quilts, just make the best quilts you can.
