Love crafting with epoxy resin? Consider picking up a tumbler turner—a relatively small and convenient machine that enables you to decorate cups by pouring, drizzling, or painting tinted resin on them. These machines suspend a cup horizontally while spinning it slowly so you can apply coats with ease. You can buy just a turner, but a more economical option is to purchase a kit that also comes with materials for mixing and applying resin. Below, find our top picks and be on your way with a fun and creative craft.
