iDye Poly is for synthetic fibers such as polyester and nylon. It even works on some plastics—buttons, frisbee discs, 3D printed objects, dolls and more! The dye comes in a dissolvable packet, so there are never any messy powders to handle: simply drop the packet in a pot of water, add your fabric and bring to a boil!
