Put four marshmallows on a skewer and lay them on the wax paper.
Melt the white candy melt according to directions on the package.
Pour over the marshmallows once melted. Let dry.
Grab a different bowl and melt the other candy according to directions.
Move the melted candy melt to a piping bag, keeping the different colors in different bags. Snip the corner and drizzle over the marshmallows. Add sprinkles.
Let them rest until set. Cut along the sides of the marshmallow before trying to pull of waxed paper.
Notes
Add teaspoon vegetable shortening or coconut oil to make the melted candy not as thick.
