This listing is for the Low Curve #10 ruler by itself. For more information on the Low Curve rulers, see the listing for the Low Curve Full Set.
The #10 is a versatile ruler, curving to a smidge over a half-circle. Based on a 10 inch circle, use as much or as little of its smooth curve as you want.
Because of the slightly thicker acrylic than the rulers typically sold for use on low shank machines, they are easier to hold in place. On a small percentage of low shank machines, they may not fit directly behind the foot, but these gentle curves are meant to be used most to the sides and front of the foot and have no need to be placed behind the foot. With the same curve on the concave and convex sides, you have options on how you place it on your project.
Switch back and forth between the concave and convex sides to best position the ruler where you can see and move best.

You must use a ruler foot when using rulers on your machine. Templates come with a protective coating that is to be peeled away before use.
