I bought one from Quilt in a Day and it's very good. I also got one from Missouri Star and it's good. Can't tell any difference. I also found pressed wool carpet mats from the carpet store that were scraps. The aren't as thick but work fine. I was having my floor replaced and he gave them to me free. My whole guild got pressing mats cut in many different sizes. I tried the wool blanket but it's not stiff enough to work like the pressed pad.
