Many of the products made have been joint projects with our kids. I want to teach them skills in the shop as well as how to properly manage money.
Each item they helped with in the shop is properly tagged with their name, the tasks they provided, and the percentage of their contribution to the overall project. Once their item sells, they make that percentage of the proceeds. My wife, Katie, and I then work with them to be money wise: Some goes to helping pay for project supplies, some for giving away, some for saving, some for spending, etc.
