I've been going to the show for about 10 years. I go with a friend, and we make a whole day out of it. There's always something new to see. It's nice and convenient to have so many vendors in one place, and we always end up buying something...sometimes four or five somethings!
A couple of years ago, I made a vacation quilt for my best friend. Each block had a picture representing one of our vacations (Seattle, NY, Grand Canyon, San Francisco, cruise....you get the idea), and I was able to find most of the fabrics for the quilt at the show. So much easier than driving around to multiple quilt stores!
