im looking to make a pasted balsa wood strop for my chrox but the problem is the one i have is a crayon, what would the best way to apply it to the wood be?

the obvious would be just draw it on and mybe smooth it with a finger, but i wasnt sure if it would be even enough or if it would clump up too much. or would i be able to mybe take a small ammount and melt it and then rub it on?
