I think we all notice our mistakes but others don't know what to look for. It's good to strive for perfection but I refuse to drive myself crazy dwelling on it but I sure do strive to do better with the next project. I put the quilt away for awhile and when I pull it out to show someone, I see it with different eyes even though I do know the mistakes are there, it's a beautiful quilt or garment and my workmanship is normally pretty good. Everyone has mistakes or goofs in their quilts as it's a human impossibility to actually achieve perfection all of the time. Now if it's a really glaring goof, that's a whole other matter and hopefully it can be caught and fixed before it's too late. I do strive to improve with each quilt, garment, new project and on occasion will do a project that I refer to as a learning tool where I experiment away - guess those turn into utility type quilts but they too get completed and are used and loved. When I need something to be as perfect as possible, I do strive for it and get close enough - no experimenting on these. For me quilting, is relaxing and a pleasure to do and this is one of thing I do for me that also directly benefits those who receive my quilts and the love that goes into them. I refuse to stress out over imperfections and in fact do show my mistakes to the grandchildren as I want them to learn that it's ok to make mistakes as long as you learn from them and improve along the way and with quilting they see the beautiful result mistakes and all but they also see that as the quilt progressed, my workmanship improves and that's the lesson I want to teach them.
