Every stitcher should own a Flexilens on Mini-clip so that you can see your stitching better and benefit from better stitches. The magnifier makes stitching easier and more relaxing for your eyes so you can enjoy your stitching for longer! The main lens is 3.5" in diameter with 2.25X magnification (5-diopter) and there is also an inset lens, which is 3/4" in diameter with 4X magnification (12-diopter) for those very intricate details. The Flexliens on Mini-clip is on a chrome flexible arm and feature a small black clip that has been designed so that it does not mark your work or fabric. It is extremely lightweight and portable and ideal for stitching on the move, so now you can stitch at home, at a class, in the car, in the garden anywhere!
