Re: Is it possible to "make my own mat"?
Hey Roy, at our dojo in we use a really nice and inexpensive marine foam, covered with a very nice canvas.
It feels very soft yet not squishy which I like very much. I prefere a harder mat actually but it is great for students who are new, and for those who are practicing falls from techniques like Koshinage, or high falls. The down side for me is that the foam tends to keep odor and you really have to maintain, and the canvas gets really slippery at times. But other than that it is very inexpensive and easy to do!
Hope I helped a little.
