I don't know about the Paducah show, but there's a little online fabric store with amazing prices in Smith Grove, KY. It's called Whittle Fabrics and I believe it also has a retail facility. The fabrics on their site are mostly closeout types, and if you like retro fabrics you'll love them. They do have some brighter and more modern things, but that doesn't seem to be their stock in trade. I have ordered from them, but have been slightly disappointed -- just at times -- in how their web pictures match their fabrics. However, I've always wanted to go visit their store to buy at their wonderful prices while actually SEEING what I'm buying (a luxury, yes? ;-). So if you need another day trip, visiting their store might be something to do.
