When we love our things, we take better care of them. With that in mind, how about keeping your Little Picaso's goodies in something she can't help but adore - like with these crayon (shown) & colored pencil roll-ups. They can be found at http://www.etsy.com/shop/twolittletots.
If you need to buy by volume, then house the motherload in the cupboard while giving your little one a great selection to work with. It's a simple case of supply & demand. Wax will abound on the carpet with crayons-for-the-masses, while the chosen few will be coveted.
Great for travel too.
