I have also attended the Sewing and Stitchery Expo in Puyallup. I have not had the opportunity to attend the Paducah show. Puyallup's Expo has lots of vendors, many of whom sell quilting supplies and fabrics, but it is not a quilt show. Most of the classes are just short introductions to a technique, meant to encourage you to buy the book or supplies sold by the instructor. I would jump at the opportunity to attend the Paducah show, which is a true quilt show, one of the premier quilt shows in the world, though certainly not the largest. I am sure the classes there are much more in-depth, and the whole town, not just the fairgrounds, is involved in the show.
