"I am afraid "they" will think my quilts are too terrible to even quilt!"
The only reason I would give a quilt back to a customer for a "fix" before quilting is if the borders are wavy to the point where I would have to make tucks either in the border or the backing to get the quilt something close to square.
Be a little patient with yourself - no one pieces like Judy Niemeyer when they first start quilting! We all have pointless stars and headless flying geese...if you really want a "perfect" quilt, you have to commit to ripping out every seam that isn't perfect, every time. I have re-sewn a seam 4 or 5 times, still could not get it right and finally said to heck with it! I'm lacking a bit in the patience department on my piecing, so I figure that if you can't see the "problem" from the back of a galloping horse... Sometimes you just have to live with less than perfection.
Now when it comes to longarm quilting...I have tons of patience and will pick out stitches as often as necessary to achieve as close to perfection as possible. Guess I must prefer to stand to pick out stitches instead of sitting with my feet up :roll:
