There is nothing wrong with you. One of the gals did a bargello for one of her first attempts at quilting and fell in love with bargello. She has made like six of them, baby quilt size, to give to friends and family as gifts for their new babies. She has done some other types of quilts but she still loves to do bargellos. Keep doing them. At some point you will find another pattern you will like or maybe go on to something new with bargellos. There are no rules and you do what you love to do!
