Check out TrueCut's Double-Sided, Self-Healing Cutting Mats for a professional-level cutting mat. They have three sizes to pick from (12" x 18", 18" x 24", and 24" x 36"), so there's the perfect size to choose from to fit your project. TrueCut Mats have a center core made of a 5-layer PVC plastic, allowing the cuts to heal faster and keep the working surface smooth. All of TrueCut's self-healing rotary mats are double-sided, giving you twice as much use! One side features bias markers for cutting bias strips, and the other has angle reference guidelines in 45 °, 60 °, and 90 ° measurements. All printed guides and numbers are easy to read, with numbers running in both directions so you can measure left to right and vice versa. The grids on the TrueCut cutting mats are precisely measured in 1/8" increments and run to the edge for accurate measurements.
