Steve has put a video on Youtube about the matt. It doesn't come with the saw. Hope nobody minds me 'butting' in on this conversation, but it's the 'only' thing I know as I have one
Yes, I've burnt the piece in this photo and will remake at 100% and I think then it will take my 'normal 13" square one, and I'm going to try and get some 'cocktail napkins' and make one to fit those too. Just for comparison.
