So glad to see this post. I've been quilting for more than 30 years and am yet to be perfect. Hardly! I agree with ckcowl - - there is only one Master Quilter. My motto is, 'progress, not perfection.' Learn from your mistakes; incorporate 'intentional' errors into your quilts as the quilters who came before us did. If I wanted perfection, I'd still be working on my first quilt.
Most importantly, be kind to yourself. Remember, this is SUPPOSED to be fun, enjoyable, relaxing; a creative outlet.
Quilt on!
