Floating around in the How Do I Price My Work universe is the formula of multiplying; doubling (2x), tripling (3x), or quadrupling (4x) your Cost Of Goods (materials and supplies used to make your item). I think this formula has been around since the first crafter sold an item to her sister, neighbor, or friend. It’s very basic and easy for those of us who are creative, but not so interested in complicated mathematical formulas. However, I think even if you use this type of pricing formula you need to make sure you are getting paid for your labor.
