The Curve Runner is a dream for measuring straight or curved lines. It is particularly useful in checking sleeves and necklines. The clear acrylic allows you to see through the ruler, never leaving your line out of site. A complete rotation is a generous 12", but just keep running the ruler to get your full measurement.
"I used to hold a tape measure on its side to measure curves, but the curve runner is much faster and accurate...I love this ruler!"
