Finally there's a more efficient and effective way to block your projects! This 38" x 50" soft, Teflon-coated surface is big enough to accommodate larger projects, but can be neatly rolled up and stored when not in use. Whether you're knitting, crocheting, quilting, sewing, doing needlepoint, cross-stitch or scrap-booked you can easily pin your project onto the surface of the mat, then press and steam it in place. The 20mm x 20mm grid lines ensure your edges, hems and seams are straight. You'll wonder how you ever did without this fantastic tool by the clever people at The BagSmith. It blocks to perfection and stores with ease!
