Everyone was talking about the wool mats so picked one up at the last quilt retreat I went to. Also picked up one of those hand size irons to go with it. Its nice to have it right next to my machine when doing paper piecing. You can get these mats in just about any size it seems too. I really like mine and the little iron I picked up to go with it. Paid twice the price though than what I could have paid at Walmart. Won't make that mistake again. Think my mat is 12 x 18 or there about.
