You can earn holiday cash if you knit your own crafts to sell. The biggest secret to success in the knit craft industry is to start early in the year. You will then be assured that your products will be ready at least a few months before you plan to sell them. Holidays during which crafts are often sold are Christmas, Independence Day, Easter, Valentine’s Day, and Halloween. Not only that, but sometimes craft shows run during other holidays, such as Hanukkah, Yom Kipper, and various Eastern holidays.
