The Supersize 5-in-1 Sliding Gauge (11 inches) is the "go-to" sewing notion! Whatever sewing you do, you'll find it a versatile and accurate tool to measure, mark and create. It can be set in 1/8 inch increments and locks and releases with a simple push slide. Use the gauge for spacing and making buttonholes, as a seam allowance gauge, as a hem gauge, as a circle compass and as a T-gauge.
