My biggest problem with quilting is picking out the fabrics. I agonize over it for days on end before I finally come up with what "I think" I want, and that still doesn't mean I will be happy with it. Sometimes I am and sometimes I am not. I have only done one Mystery Quilt, and picking fabric out for that was even worse, cause I had no idea where the different colors were going to go. Other than that, it was fun, and the quilt turned out really nice.
