OLFA 35 x 70" Continuous Grid Connecting Rotary Mat — 3-Piece Self-Healing Cutting Surface with Clips

OLFA's 35 x 70-inch continuous grid rotary mat system joins three connectable mats into a large, self-healing cutting surface ideal for fabric, quilting, and pattern work.

This three-piece OLFA rotary mat set (three 23" x 35" mats plus four clips) creates a nearly seamless 35" x 70" work area when clipped together. Each mat features a self-healing surface that helps blades last longer, and the double-sided design gives you a gridded side for precision measuring and a solid side for general cutting. The modular format stores and transports easily while giving you the reach of a large single mat when you need it.

How does the continuous grid system make long cuts easier?

The connecting clips keep individual mats aligned so long, straight cuts glide across the seam with minimal catching. The grid lines printed on one side provide visual guides for squaring up fabric and lining up long rulers.

• Three 23" x 35" mats clip together to form a 35" x 70" surface
• Grid lines on one side for accurate straight and angled cuts
• Four metal clips hold edges flush to reduce seam lift

What should I know about the mat's self-healing surface?

The mat layer is formulated to close small blade cuts, keeping the surface smooth and preserving ruler accuracy. Proper use — rotary cutters only and flat storage — extends the self-healing performance and reduces warping over time.

• Self-healing finish reseals small blade incisions
• 1.5 mm thickness balances stability and blade protection
• Avoid fixed blade utility knives; store flat and out of sunlight

Which side should I use for what jobs?

Use the gridded side for precise measuring, alignment, and cutting repetitive pieces; flip to the solid colour side for general cutting where the grid could distract. Both sides protect work surfaces and prolong blade life.

• Grid side: measured cutting, squaring, and angle work
• Solid side: larger freehand cuts and pattern tracing
• Double-sided use prolongs overall mat life by alternating wear

How do I care for and store these mats to keep them flat?

Store the mats flat or hung with even support; avoid rolling or exposing them to direct sunlight or extreme heat. Clean gently with mild soap and cool water if debris or adhesive marks appear.

• Store flat to prevent warping; do not roll tightly
• Keep out of direct sunlight and excessive heat
• Wipe with mild soap and cool water; avoid harsh solvents

Who is this for: Sewists, quilters, pattern makers, costume designers, and any maker who needs an extended cutting area without committing to one giant mat. The OLFA continuous grid system suits hobbyists and studio users who value accurate measuring, blade longevity, and the flexibility to break the mat into smaller pieces for storage or transport.
