The GO! Cutting Mat by AccuQuilt is a 5" x 10" mat designed to work with the Go! Fabric Cutter and GO! Baby Fabric Cutter (sold separately). It is compatible with various AccuQuilt GO! dies, including the 3-1/2 inch Square Die, 3 inch (finished) Half Square Triangle Die, 3-1/2 inch x 6-1/2 inch Rectangle Die, 3-3/4 inch x 3-1/2 inch Parallelogram Die, and the Funky Flower Die (each sold separately). This specially formulated cutting mat is an integral part of the AccuQuilt GO! Fabric Cutting System's precision and efficiency. To ensure longevity, avoid exposing the mat to extreme temperatures (intense heat or cold) as this can cause damage or brittleness, and keep it out of direct sunlight. Imported.
