My lumber crayon in my tool pouch was always destroyed by my other tools. So I decided to make these crayon holders from scrap 1/2-in.-dia. copper pipe. Cut the pipe slightly shorter than the length of crayon, then take the wrapper off the crayon and insert it into the pipe. It’s a tight fit and the pipe may scrape off some of the crayon, as shown in the drawing. As you use the crayon and it wears down, push up from the bottom.
