You can use Rit dye to mix vinyl in many types, from plastic upholstery stuff to a doll, sandals or even a disc-golf flying disc. Based on the desired color for your project, Rit may be used directly from the package mixed with water, or together with other Rit shades to make your own custom tints.
Cover the work surface using a plastic tablecloth to safeguard it from wax. Set a plastic tub atop the tablecloth.
Add hot tap water to the plastic tub working with a number recommended on the Rit package; the amount can vary based on the kind of Rit dye used. Mix in an appropriate quantity of wax, after the Rit manufacturer’s directions. Stir with a spoon until the dye is thoroughly combined with the water.
Wipe the project piece using a moist sponge, if dirty or dusty. Wipe dry with a paper towel.
Immerse the vinyl item face-down from the dye mixture while wearing rubber gloves. If the item floats a bit, cover it with a moist cloth or rag to help keep it submerged, or hold it down using a plastic spoon, then keeping it beneath the fluid surface without touching the base of the tub. Expand the item every few minutes when working with an object like a vinyl doll.
Lift the piece from this dye after 10 or 15 minutes while wearing rubber gloves to find out whether it’s reached the desired shade. Otherwise, set it back from the dye solution for several more minutes. After removing the vinyl from the wax, hold it above the tub until it stops dripping.
Set the vinyl item atop an upturned can or plastic storage tub, based on the size and shape of this project slice, till it dissolves completely.
