I never sold many tarts because they swere such a pain to package. Tried paraffin in tart molds, silicone molds, container wax in the foil cups - nothing was right. Then I started the clamshells. They didn't sell much better but I just kept at it. Now I sell them pretty well on website and at shows I can sell a hundred+ easily. 'Course a 4 for $ price helps sell the multiples at shows. I also do the 1oz little black portion cups with my last bits of wax and just write the name on the lid. I bundle up about a dz and hand them out when you buy a tart warmer. Plus I bundle up a big bag for friends and family for $5. Just enough to pay for the costs and they get some treats.
