I think the first thing you should do is attend a quilt show. This will allow you to examine all the quilts in the different categories. Some shows will even have a category for "first time entry". Some people think this is just for the younger quilter, but normally that is a separate category in itself. The "first time entry" category is for someone like you who has never entered a show. Quilt show categories can vary between shows but I'm sure there's one for you. I have learned the most from judge's critiques by entering shows. Good luck. It will be fun.
