Your quilts are gorgeous. And they are sure to win ribbons. I have 2 quilts entered in a show the same weekend.
When filling out the form, you need to check off if it is your design or a traditional pattern. Changing the colors does not make it your design.
The judge takes a lot into consideration when she gives her points. The binding seems to get a lot of attention and it will bring your points down if the binding isn't perfectly done. The quilts are put into categories: hand quilting, long arm quilted (by a professional) or machine quilted, plus many other categories.
At our guild, each quilt is judged on its own and will get a ribbon when points are added up and it totals a certain amount. We pay to have our quilts judged and we compete against ourself. For if quilts are judged in categories, say there are 20 quilts, there will be a first, second and third place ribbon. But if each quilt is judged on its own, that quilt can either get first, second, or third, or no ribbon. So this way, we have a better chance of getting a ribbon and more people are happier!
The judges "study" for 5 years and have to pass a test, piece and quilt a quilt before becoming certified.
IF, IF, IF I get a ribbon, the judge will write what is good and not so good about the quilt so that I can work on improving my techniques. So it is a learning experience.
Good luck and hope you get a ribbon for each quilt that you enter.
