Chiming in with everyone else, just go ahead and do it. Don't hope for perfection, just have fun. I guarantee that no matter how many mistakes you think you've incorporated in your quilt, you're the only one who will ever see them. As quilters I think by definition we often can't see the forest for the trees. And we're also our own worst critics. I finally made myself stop ripping out. Most of the 'horrible' stuff really wasn't, and the really dreadful mistakes encouraged some pretty interesting 'corrective' applique. And all told it's just an excuse to indulge our fabric addiction and play with our toys........LOL.
