The wire rack was actually an old closet shelf that I wasn't using. I will also be doing 2 indoor fairs beginning of Dec and need to think about other ways to display. I'm going to check out freecycle and craigslist for shutter doors. A coat rack will be hard for me to transport. Will let you know what I come up with!
I've only done 2 craft fairs so far and received several orders from both for custom orders. I also make handbags, totes, wristlets and the likes. I bring a binder with all of my fabric selections and let the customer choose from that. Take full payment including shipping fees. I use a carbon receipt book so that they get a copy too. So far it has worked out great for me.
