It’s supposed to be fun. Do the best you can at the moment and enjoy looking back and seeing how far you come over time. If you spend all your time stressing and redoing something over and over trying to reach perfection ( which, by the way is impossible and unrealistic- look at Nature’s *perfection- every leaf or snowflake different) you wind up losing the joy of creating. Do your best and move on. 10 years later you look at that quilt you made 10 years ago and see- wow, I’ve really come a long way! It doesn’t make you like it less, you just get to see and appreciate your improving skills.
