Giving you plenty of traction on virtually any fabric, Grip-Its let you easily control and adjust fabric when using a sewing machine. Each Grip-It is made from 0.25-inch-thick clear acrylic and has heavy-duty rubber grips on the bottom that help you guide your fabric while stitching. The clear acrylic allows you to see your pattern and track your previous stitches, while the D-shaped design of the grips provides a straight or curved edge to guide repeating patterns.
