Pure and natural 100% wool - directly from the sheep, fleeced and tightly felted to make the Quilter's Pressing Fleece the perfect ironing surface for all your quilt block and small pressing needs. Steam or other sprays are unnecessary because the wool actually absorbs moisture from the air as heat is applied. This creates an addition heat source underneath your fabric giving you crisp precision as you iron. This is by far the best ironing surface ever - it is truly fabulous! One of those investments and tools you won't want to be without whenever you sit down to sew. The Quilter's Pressing Fleece is designed to keep near your sewing area for all those quick little presses - which is perfect right beside your sewing machine! Having it handy and at your side means less time getting up and down and more time sewing! Includes an easy-to-carry, high quality, canvas zip-up carrying bag that protects the fleece and is easy to carry and store. Bag is large enough to also hold a 12in x 18in cutting mat, ruler, and other quilting products. Pressing Fleece measures 12in x 18in.
