It takes more than 2or 3 days to see and do it all - In addition to the fabric shops and quilt displays (even at the local mall)- Fashion Show is good, locals put on evening play as excellent entertainment; churches provide lunch and tatting demonstration; very nice eating places (some require reservations in advance) downtown
If you don't have a friend to go with, check for bus trips. Call Chamber of Commerce for brochures of activities. I love this show more than Houston! Going again this year.
