I have not bought a wool pressing pad yet but have heard from Watson (board member) that you can purchase wool horse pads online that are less expensive from quilt shop/stores. State Line Tack has
good prices. You can get a 30"x30"x1/2" wool pad for $21.97. You could cut it in half & get two 15"x15"x1/2" pads that would equal $11 per pad. Not a bad deal in my book. Their site is:
www.statelinetack.com
Hope this helps....like I said, I've never ordered from this place but looks like a good deal to me.
Search under wool pad liner to see the plain, simple wool liner that they have available.
