I have one from Joannes and use it on my big table where my machine is..it is used for everything, including rotary cutting. The only problem I've had is when a friend cut all the way through it! She didn't know she did it, and I"ll never tell her - while that particular cut didn't "heal" it is invisible unless I know where to look for it. If nothing else, the mat is a great work surface that proctects your table/counter.
