For me, I also post photos of all my quilts as soon as they are finished, so I rarely or never have one that hasn't already been posted here on the board. Also, having only been a quilter for 2 years, I don't really consider myself qualified as a contest entrant.
All of the quilts I have finished have gone off to new homes so I can't measure them and I haven't kept records of their exact sizes. I know if they were throw, twin or full, etc. but that's about it.
I do enjoy seeing the quilts entered tho, and if I happen to see the contest info, I like to cast a vote.
