I am not perfect nor do I aim to be. I quilt for my own personal pleasure and only make quilts for a few beloved family members on my time schedule. the rest I make just to make them and they will get donated one day. So, if a quilt is a little "off", and it isn't major, I just go with it. I made a quilt and had it over a bannister and a visiting friend said she loved it. I gave it to her. She is thrilled with it. She isn't looking to see if the seams line up, etc. I do try to make things as good as I can. Most of mine are pretty good. Perfect? No. Do I rip apart? Very rarely only if will affect the final outcome on a big scale.
Something else I realized - not many people but other quilters and quilt judges look at the actual quilting. I love to FMQ. It is my favorite part among all the other parts I like too. I have been perfecting feathers, swirls, etc. They are very time consuming. I had a quilt I wanted to finish and I can do a wonderful meander. So did that. The recipient raved about the fabric choices - never noticed the quilting. So I'm guessing unless it is for some other quilter (not from me) or to be entered into a show (not doing that) I will keep my fancier FMQ for when I am bored and for something that I don't mind keeping around for a long time to finish. I even think wavy lines are fine for most quilts. I have done that a lot of times. I don't like Stitch in the ditch. To do or to look at. That is my preference. Not saying anyone else has to agree or do what I do.
