I wouldn’t want to run a home without this small sewing and knitting gauge (approx. 6 inches long, metal with a movable plastic marking guide) Helpful for all household projects which require consistent simple measuring and marking. Used for craft projects, or just to help children learn how to measure equal distances when they want to do some kind of art project requiring parallel lines. The small size makes the gauge convenient to cart along for measuring/adjusting/adding lines of sequins, or decorations to costumes. Most families need to hem things (blue jeans, curtains, skirts, costumes) and the gauge is PERFECT for this use. This is as basic a tool in my home as scissors or a ruler. Can be purchased in any sewing store or the sewing department of a discount store.
