If you have some crayon stubs that your kids use no more...then just mail them to Crazy Crayons. This is the name of a crayon brand, brain child of LuAnn Foty that is engaged in melting down the old crayon stubs to make out new crayons in unique shapes - recycled crayons in short.

Crazy Crayons crayons are available in 26 shades and come in a recycled cardboard box, containing tree-free scribble paper and that is finished with a straw grass ribbon. Isn't a great way to dispose off the crayons in a meaningful way...which otherwise would've been thrown away just like that
