This oversized wool mat holds heat to press from both sides, giving flatter seams and crisper points on large blocks and borders. Made from tightly felted New Zealand wool, it absorbs moisture and often needs little to no steam. The 18 × 24 in footprint suits cutting tables and boards, while the ½ in (13 mm) thickness stabilizes fabric to minimize stretching. Pin for blocking as needed. For best results, use without steam, store flat, and avoid placing on cutting mats.
