By simply putting the Quilter's Slidelock on your fabric and pressing down on the middle of the handle, which requires very little pressure, your slippage worries will be a thing of the past. The patented design springs into action (pun intended) when you press down on the handle. When the handle is depressed, springs engage, allowing special bumpers on the bottom of the handle to travel through precisely cut holes in the base, causing the bumpers to grip and hold your fabric in place. It works so well, you can even cut up to 10 layers of fabric at once without having to worry about slippage. Additionally, at 24" long by 3.5" wide and made with 1/4" thick acrylic, it is long enough to cut all your favorite fabrics in one pass.
