What is your normal weather like from June to Oct?? Is there suppose to be a lot of rain this summer?
Trust me, outdoor markets and soap do not get along in rainy weather...
A 10x10 pop up tent is good. You'll want to get some coffee cans filled with cement to tie the tent legs to in case of wind.
Will they assign you a specific place at the market? Or is it first come, first serve for booth spaces each Saturday? Once you are there, you'll want to be in the same place every week so folks can find you. Get to know other vendors, give out sample soaps to them so they can help market your booth. Signage and a pretty display help attract folks to your booth.
Make your display multi-tiered instead of everything flat on the tables. (shipping boxes covered with fabric is easy and cheap!
I've participate in a year 'round FM for the past 4 years. (helped start it up.) 2 weeks ago I finally shut down my booth until mid-May. We don't get the customers during the winter months and I end up spending $ and 5 hours every Sat for nothing.
The market board just initiated a new weekly booth fee. Minimum $5 plus 10% of sales, maximum of $10 per week. The vendors asked for a straight yearly fee since the months from January through May are so slow (maybe 30 customers in the market the whole day).
We thought that since we would be paying booth fees during these slow months to help keep the market open all year, they would cut us a break. Nope! So I said, see ya in May! And another vendor followed suit.
It was an economic and political move on my part. The board used to be made up of business folks, chamber of commerce & vendors, but they decided 'some' of the vendors on the board weren't playing well with others. (what can I say?) so they decided the board should be made up of with only one rep from the vendors. The board was suppose to solicit $ businesses and find us grants .... I won't go into all of it, but let's just say our $10 in the bank was spent by the board in 2 years for 'special projects' and now we don't have $ to pay utilities.
