This may seem a little silly, but pencil pouches have been a lifesaver in our house.

Big Sis has always been a creative girl. As soon as she could grasp a crayon, she marked, drew, shaded, cross-hatched, painted, splattered, and glued her way through a myriad of projects. As she grew, so did her collection of art supplies.
Around Christmas we realized things were a bit out of control. A purge was in order, and purge we did. And then surprise! Mom and Dad provided a new array of supplies to enhance her creativity - complete with pencil pouches to secure her new rainbow of twist-up crayons & pencils. Now she knows where they are, and more importantly, which crayons are hers & which are her brothers.
**PS, if you haven't used twist-up crayons or pencils, you're missing out. Awesome.
