My son loves to make money. He's 8 and wants to make a craft to sell at when I do craft shows. We came up with these little Halloween and Harvest favor bags to put some candy or chocolate in. How much should I charge? Also I make these vases with potpurri, lights, a tart on top and then a doily with ribbon. They are just not big sellers for me. What should I charge for these also? Thanks for any feedback.
