I am a cozy quilter. Made 2 wall hangings to give as gifts this Christmas and both had mistakes. Not all of my corners ever meet up nicely. But what counted what the love, time and effort put into those wall hangings and the reciepients were thrilled with them and didn't see the booboos. I try to keep a journal and learn from my mistakes but I try for "Am I happy with the quilt?" and not perfection.
