I purchased this 17 x 13 1/2" wool pressing mat for only $18.99 plus tax with free shipping, and I am so pleased with it, I will be ordering another to give as a gift. It arrived in only 4 days and is exactly what I wanted. Thought I'd try it as the price was so reasonable, and I wasn't disappointed. If you're not sure if a wool mat is for you, and don't want to spend a lot of money just to try one out, this one may be your answer.

I noticed today, that the price has been increased to $21.99. Guess I did get a really good deal!
