Design for crafters, OLFA self-healing rotary mats are 1,6mm thick, double sided, triple layer mats with a dark green base color and yellow grid lines with a metric grid on one side and an inch grid on the other. Grid lines are designed for easy measuring and for accurate cutting of straight lines and precise angles. The markings take the difficulty out of such tricky tasks as fashioning true bias strips, cutting strips into squares and triangles, and perfectly squaring up blocks to complete a project.
Self-healing, an OLFA original technology refers to the ability of the surface to return to its original shape after being cut and are ideal for general quilt cutting. A three-layer structure ans soft cutting surface realize smooth cutting even after many years use. Rotary mats protect your work area and greatly extend the life of your rotary blades
