Self-Healing Cutting Mat: Cork Pinning Side and PVC Cutting Side, Tri-Fold (Carnegie, US 11,077,575)
A self-healing cutting mat has a PVC face that closes up again after a rotary cutter runs over it. L. V. Carnegie (US 11,077,575, 2021) glues a cork layer to the back of the PVC layer, so the same board takes straight pins on one side and cutting on the other, and scores it so it folds in three for storage.
Which PVC heals is not given: Carnegie only says PVC mats are self-healing.

Cut the two layers
Cut the two layers
Cut a PVC sheet and a cork sheet to the same size. Carnegie: each layer 1/8 to 1/2 in. thick (cork 1/4 to 1/2 in.); one mat is 72 in. long by 40 in. wide, but any size will do. The PVC grade that self-heals is not given.

Score the folds and mark the grid
Score the folds and mark the grid
Score two lines across the full width, partly or fully through the layers, so the mat folds into three panels with its faces inward. Print measured grid lines on either face, or stick on a printed paper grid. How deep to score is not given.
