First, if you have to unwrap a bunch of crayons (especially if a bunch of them are broken), an x-acto knife is your best friend. Just carefully slice down the wrapper, and then easily peel it off.
Second, this may just be personal preference, but I don't really like just throwing a bunch of colors together. I grouped colors together in a sort of theme (Halloween, camo, sky, lipstick, ocean, midnight, and sunset):
This is a great way to recycle old crayons, and mix in some of the cheap-o generic crayons that don't ever get used. They are perfect for small hands.
They are a favorite of my two-year-old. We've also had fun stacking them, and counting them.
