The SimFlex Expanding Sewing Gauge gives you the ability to perform quick and accurate measuring, and is easy to use. Works in sewing, arts and crafts, or even gardening and cake decorating. The gauge marks and evenly spaces buttonholes, drapery and clothing pleats, tucks, shirring, smocking, and more. It is flexible and lightweight, making it even easier to use. Quilters often use it to mark cross-hatching, evenly divide quilting areas into equal segments, and repeat individual quilting designs. Simply lay it over the fabric or item you are marking and expand to the desired length to achieve perfectly measured equal distance and accurate spacing, anywhere between 3/8 in to 3 3/8 in.
