I purchased the Magic Mat knowing that it would be too large for my very old Cuttlebug machine. When it arrived, I used a metal ruler and a craft knife and simply trimmed a little from each side of the mat so it fits perfectly. It was not difficult or time consuming to do, I used an existing plate as a guide. I did need to add a small shim underneath it (I used a thin piece of card) to get the best cutting results. The rest is magic! Lovely clean cuts, no more fuzzy little hairs hanging off, and that cracking noise that give me palpitations is gone!
