I said to myself, "what the hay??" on those pressing mat prices! So... I found a great site (EcoRugPads.com)that cuts a 3/4" thick pure wool felted pieces any size you request, and ships for free, and quick. They have all types of material.. but, I chose the 100% wool, called Nature's Cushion. It may not be as thick as the 1/2" size, but it works just the same. For about 18.00. If you want it thicker, you could probably sew two pieces together. Works great!
