Made from durable plastic, this expandable sewing gauge has easy to read markings with inches on one side and centimetres on the other. Makes measuring multiple equal distances easy. Great for marking buttons and buttonholes, hook and eyes, snaps and much more. Once finished, the gauge folds neatly away to be stored in your sewing stash. The gauge measures (w/l) 7.7 x 15.8cm when closed and extends up 61cm. Do not wash.
