Wool Pressing Mat 22" x 60" – Extra Large 100% New Zealand Merino Wool Ironing Mat for Quilting, Sewing & Crafts – Sets Seams Flat, Heat-Retaining, Portable Quilters' Board

Exactly as described and perfect on my Big Board that's at least 15 years old! I worried that it might be too thick for under the board's cotton covers, but it fit as described and the cover fit on top just great. I don't know why I didn't find and buy this sooner, I just didn't look or know such a thing is available. I saw one offered on a sewing notions site, looked into it further and found this one substantially less expensive. It is a great cushion so seams don't imprint and the steam iron penetrates making ironing easier and more efficient. (A Big Board is the large size mat, 22 X 58" I believe.)

This works amazing. There is no smell when ironing at all. The size and price was perfect for my sewing space. Great product!

The mat is huge! I have a bigger than average size ironing board and it covers the entire board and then some, it's nice and thick too

Top notch pressing mat, and no wooly odour. However - and this was my mistake - a water barrier is imperative. I used the mat on my cutting board, used a steam iron, and left the mat on the table overnight. Of course, the water from the mat damaged my cutting mat.

Thick and perfect!
