Please enter it. If you were asked by another quilter to enter it, she must have thought it was show worthy. I enter quilts so that other people can say 'I could do that'. Think of the number of people who will see and love yours. Sounds like a huge show!
I will say I am jealous. My local guilds shows are not judged. And when I have entered quilts into the county fair, I have won ribbons, but there are no judges comments - good or bad.
