I made some of these for my Grandson and used heavy construction paper the same colors for the labels as the crayons were. I made blue, red, green, yellow and purple. I colored the crayons with oxides and FD&C coloring, they were dark and wrote (marked) well. They melted pretty fast. I don't know why, maybe I should have used more beeswax I don't know. I used blue paper (not blue ink) with this one. I put them in a small plactic bag and made a label that was the width of the bag folded it over and stapled it shut.
