I used to do Junior League shows in another business. The first year i had the pottery I did Tinsel & Treasures in Lafayette, LA. http://www.juniorlea...com/?nd=tnthome
This is not the best Junior League show but it is the first of the season and has lower booth fees than most Junior League type shows. The booth fees for a 10x10 range from $1000 to $1350 at T&T. It's a 3 day show, with a preview party. My sales here were $7800. I did not consider it cost effective as I was gone 6 days, 5 nights in a hotel and took a paid worker with me. My break even point was about $4k (gas, meals, hotels, COGS, booth fees). The best shows of this type are in Texas. I used to go from Chi Omega Christmas Market (Dallas) to a Christmas Affair (Austin) to The Nut Cracker Market (Houston). I really don't find these shows cost effective for a hand crafted product but I do know this one potter that does Holiday House in Little Rock AR, and it must work for them because they have been doing it for years. I'm sure I could have increased my sales if I continued to do those type shows but it comes down to the fact that I don't want to have to make that much pottery to break even. Plus I have 100% sell through in my retail shop, which is in front of my studio.
I did do a garden show in my other business and found it to be profitable but not nearly as profitable as Junior League shows. It comes down to the fact that you have to make pottery. Your prices would have to be hand crafted prices, not art prices and you would most likely sell well at these venues. But it comes down to production ... you can only produce so much. Not sure about spending that much just to break even.
If anyone is ever interested in these type shows, feel free to contact me as I have done most of them.
