The number one thing to find out is what the rules are for entering the quilt - quilts. If there is a judge there that you can google and check a site to see what the pet peeves are it is in your best interest to do so. If this is just a local entry and more for fun and enjoyment it will still do you good to check out what the requirements are.
Number one rule to remember... make sure your quilts are totally free from pet hair. Its the simple things that will not even get your quilt considered.
Have fun with your contest and wishing you luck on your entries. We have won at juried shows before and it is very rewarding to get the ribbon. I found the judges remarks to be the most helpful.
