Quilters and sewists, this TrueCut 12.5-inch square ruler is a game-changer for precise fabric cutting! The special feature? It has a track along the edges that interlocks with TrueCut Rotary Cutters (sold separately) to keep your cutter from slipping off the ruler. That means straighter, safer cuts every single time.

Plus, it has built-in holes along the entire surface that you can use to mark your fabric with a pen or chalk. Made from durable, clear acrylic so you can see your fabric underneath. Whether you're a beginner or a pro, this ruler helps you cut with confidence and accuracy. Say goodbye to wobbly cuts and hello to perfection!
