I would do one of two things. I would keep them 'as is' just as a reminder of your quilting journey and enjoy them for that reason alone. Or, if I did not find pleasure in that memory, I would take them apart and redo them and enjoy them for the progress you have made since you started to quilt. If you do the later, maybe you could set aside 30 minutes a day to take them apart so it isn't a huge burden. And, like mentioned above snip the line of stitching every few stitches and gently separate the layers so you don't distort the fabric dimensions. Then, re-do them.
