Help needed

I am helping my husband in organizing a Christmas market. We are supposed to get stuff that can be easily sold like small Christmas ornaments for the house, gifts for family and friends. We would like to get most of these things free since the earnings from the market will go wholly to support Dynamo Camp. I am planning to knit some small things like scarves and hats for kids, and make ornaments for Christmas. I am open to ideas of things that can be made (easy and not very time-consuming stuff; probably with patterns/models/explanations) and sold at such a market. We are also looking for volunteers that would contribute with materials (yarn, buttons, tissues etc) and most important of all time. Would YOU help me realize this project by giving me something that you have made? Would you knit/sew for this market? Or would you have some other things that you produce/sell and give us free for our market?
