The 24" Quilters Slidelock is an excellent tool for cutting strips, borders, straight and bias bindings and more. Easily holds up to 8 layers of fabric motionless while you cut. Trim away excess backing and batting after quilting. Quickly smooth fabric after placing it on the cutting mat with a single swipe of the 24" Slidelock from one side to the other. Cut single layer strips into same size quilt block pieces with excellent results. Regardless of the color or type of fabric in use, when you place the Lighted Edge Slidelock on your fabric, a well-lit, clearly defined cutting guide edge appears. Perfect for quilters who may not see as clearly as they once did. Highlights all fabric colors, prints and shades. Excellent for use in dimly lit class rooms or anywhere lighting is a problem. The Lighted Edge Slidelock base color will never fade or change. No batteries or bulbs required.
