I think it's worth trying. Though if you're the type of person who really can't handle rejection, you may not want to. I entered a quilt in our Guild Show 2 years ago, and I was so excited since I had worked so hard on it, and I wanted to win the ribbon they give to new quilters that the guild votes on, and I knew I was going to win... well, I didn't win, and my quilt judge was absolutely horrible - she said everything was fair except for my points which were poor and I spent FOREVER matching up the points with the 3 pin method and they were pretty darn good if I do say so myself! I was so discouraged I came close to quitting quilting. It took awhile to recover, but once I did, I said I wouldn't do competitive type stuff like that since I can't handle rejection/non winning very well. I would still say try it, but be careful about getting too obsessed with having your quilt for sale, ya know?
