Amy Here with a Three Minute Video that gets right to the point! This tips such a no-brainer I'm frankly surprised the dies don't come this way; use it with the thicker, more durable steel-rule dies which are sharp and protected with foam and/or plastic material (for your safety) such as Sizzlets, Big Shot. Tim Holtz, Stampin' Up! and more, used with manual machines.
(For the thin metal Spellbinder/Cheery Lynn type type dies, see my organization technique video using CD cases!)
