Quilts typically do not sell at craft shows. It's more the kitch that can be made and sold cheaply. But with the economic downturn even those venues are getting little traction. I have sold on ETSY and prefer it to eBay as the overhead is lower. What I really prefer(and what comprises most of my business) are custom orders. No inventory risk involved for the time spent. Most business is WOM but I am working an Internet marketing plan.
BTW. I am a handquilter so I have to emphasize the difference between hand v machine (long arm) v big box store.
