Cover your worktable with a heat‑holding wool surface for fast, flat pressing on large projects. The 24 × 36 in mat is made from densely felted New Zealand wool that absorbs moisture and radiates heat back through the block, reducing the need for steam. A ½ in (13 mm) thickness helps keep pieces stable to limit distortion. Pin for blocking as required. Avoid steam, do not place on a cutting mat, and store the mat flat to maintain its smooth pressing surface.
