I've really been using up the crayon/marker roll idea. I really think it's a great little gift for anyone who has (or, like me, collects) pens, pencils, markers, or crayons. Slide the utensils in, roll it up, velcro shut and it's quick organization inside a bag or purse.
For a lady who I volunteer with, I made six pen rolls. She is planning on giving one to each of her children's teachers. (One being a man, for whom she requested a "manly roll".)
I used the Pleated Poppy's crayon roll tutorial when I first made this project. One can use velcro, snaps, buttons, elastic hair ties, etc. for the closure. I prefer the heavy duty iron-on fabric because I think that it will hold up for a really long time.
