Also - when you do sell individual cookies, how do you label/package... do you up your prices? By how much? Offer a discount for purchasing a certain quantity? Sell only individual cookies or also sell gift boxes / only sell gift boxes? And what sorts of designs do you make for your cookies? Or any other sort of general market advice??
You can see how I package from the pictures, on the back I have a little plain (but pretty!) label following our local cottage food law guidelines. I googled and found a template in a brochure about cottage food laws available online. I also added my Facebook on there, too. (not that anyone ever looks lol)
My first few markets I did sets but they were hardly touched, honestly. Same with bouquets and pops. We eventually only did individuals.
As far as designs.. MARKET THE KIDS!! They will cry and whine and scream until they get their favorite character!! Ask your Facebook fans what THEY want to see and they'll be more likely to come.
Offer contests for free cookies and one of the requirements to win is to come to the market. Nothing attractspeople more than the chance at free stuff!!
