I love crayons! Coloring is always blast, right? I found a tutorial for a crayon roll on skiptomylou.org and sewed one up for a friend.
The tut directions called for two pieces of 5x16 1/2 inch fabrics, one light weight interfacing at the same size, and one 6x16 1/2 inch fabric piece folded in half. It was a cinch.
The only thing I would change is I might make the next one 6x16 1/2 instead of 5x16 1/2.
Sorry the picture quality is so poor.
