DIY 2 Ingredient Crayon Lipstick Recipe and Tutorial from Oh So Pretty here. A video tutorial is also linked. Note: it is recommended to ONLY use CRAYOLA CRAYONS - not generic crayons made in China that may contain lead or who knows what. Really not sure about this - but how great would this be to make strange custom colored lipstick for Halloween?
DIY colored candles. Though, one pinned says this wax may not melt in the microwave. Guess we'll have to try other techniques if it doesn't in fact work! Also, not sure how crayons would smell as candles when melted, but maybe some essential oils / scents would help?
