Set a limit. First, decide which holiday you are crafting for, and working a month or two in advance, craft a few specific products. Don’t go overboard with it. 3-4 different products that are geared to a specific holiday is just plenty. Then, you must pre-set the last day that someone can order or purchase one of those products. Keep in mind how long it takes to create the craft, and then shipping times.
Last of all, market your sales. Many holidays come with exciting savings. OR, after the holiday has passed and you are ready to get rid of your remaining inventory without taking a huge loss in profit
