If you do ANY amount of die cutting then you know how aggravating those plastic plates can be.
Well, I figured out how to NOT use at least one of them. Replace the bottom plate that you would normally cut on with a self healing cutting mat. A 5 X7 Inch Self Healing Cutting Mat should fit most cutting machines but you can buy a bigger one to cut down if you want/need a particular size. Check the fabric or drafting section of your craft store.
AND it works well even through a magnetic plate- another grand investment!
This has seriously cut down on a lot of frustration when I'm die cutting.
