I have always done well with themed fabrics and like the coaster set and apron ideas. A few years ago, I had a friend that made 8" round cocktail napkins in sets of 4 with themed fabrics and serged edges. When we did our annual show, she'd sell them by the dozens. I have never taken credit cards as I only did 7 shows every fall, but today no one carries cash any more so I am wondering if it would hurt sales if I can't take cards. I agree that the thing that I missed most when I quit doing shows was the new customers and the wonderful people that would return year after year to buy from me.
