SUPERIOR PERFORMANCE: 100% New Zealand wool, ½” (13mm) thick, the dense wool fibers reflect heat, ironing both sides of the fabric simultaneously for quicker professional-level pressing. CUSTOMIZE YOUR PRESSING AREA: ProPress links lets you join any number of mats together to create your ideal pressing space. The links made of durable, high-quality, heat-resistant silicone are reusable over and over. Links fit snugly in the mat, creating a smooth pressing surface, and preventing the mat from sliding. Each mat is sold separately and includes four Links. IDEAL FOR QUILTING AND SEWING: the smooth, firm surface is excellent for blocking, embroidery, pressing seams, and everyday ironing. The natural wool fibers hold projects flat and in place, helping to prevent stretching while pressing. ProPress mats work great with Oliso Mini Project and Smart irons. PRACTICAL SIZE: 14” x 14” (35.6cm x 35.6cm) mat is large enough for most pressing projects and convenient placement next to your sewing machine while still compact enough for easy storage and travel. Join several mats with the ProPress Link system when larger areas are needed. QUALITY AND PERFORMANCE: Oliso strives to simplify your life with tools that work for you.
