Hi Meagan,
I had my very first craft fair yesterday and I asked this same question. I got some great responses. Here's the link:
https://www.etsy.com/teams/8070/craft-fairs-its-a-living/discuss/14406690/page/1I spent the last couple of weeks before the fair making display items:
Tablecloths
Tabletop display stands and a standing display stand
Ring display
Decorated baskets to hold my smaller stuff
Price Lists in frames
A frame sign to hold my "Custom Orders Accepted" sign
Google "craft fair display" for ideas.
I was super nervous yesterday morning. I was thinking things like, "What if people don't like my stuff?" "What if I forget something?" The other vendors were great. Everyone loved my stuff and, had I forgotten something, the other vendors were so very helpful that I would have had no problem borrowing something. Relax and enjoy your day!
