I have a sizzix big kick that you crank and used a Go die that cuts six 2" squares at once. I used a shim (2 manilla envelopes folded) and the process was quick and easy. I noticed how much more accurate it is than when i rotary cut even carefully and properly..some are off just enough to require trimming. There are probably better systems (as in automatic, bigger/faster) but this is not something i will do often esp given there are so many pre-cuts now for the basic shapes.
