Does anyone know how i can die toilet paper rolls differant colors with out getting the rolls all messed up?

Question

its for a school project. please help.

Answer 1

dry powder paint, like tempra that comes in a can of dry powder, brush the powder on like a woman does makeup. or dry brush the roll....meaning dip your paintbrush in the paint and wipe all but all of it off on the side of the container, then frantically brush the "empty" brush on the cardboard.  This helps keep the moisture down to a minimum and usually dries quickly, not allowing enough time for the moisture that survives the process to damage the roll.

Answer 2

dip different parts of it in dye, then iron after drying
