French Curve for Patterns, Comma Shape – 29.9×12.6 cm

Comma-Shaped French Curve for Drawing Curved Lines

A transparent comma-shaped French curve, 29.9 cm long and 12.6 cm high, with pink centimeter markings along both edges. The rounded end has a sharp curve and five round holes of different sizes, and along the tail the curve gradually opens into a wide arc. The ruler is printed with COMMA SHAPED CURVE RULER.

This shape is exactly right for the short, deep lines of a pattern: the armhole, the neckline and the sleeve cap. The transparency lets you see the pattern lines underneath, and the graduations let you measure the length of the curved line itself, for example to compare the armhole with the sleeve cap.

Common Uses

• Drawing the front and back armhole.

• Drawing a round, deep neckline.

• Drawing the sleeve cap and checking how it fits the armhole.

• Drawing collars, flaps and rounded corners.

• Marking small circles with the holes, for example for button placement or rounded corners.

Professional Tips

• Draw in pencil first, and go over in pen or chalk only after checking.

• Mark at least three points for each curve in advance, and look for the section of the ruler that passes through all of them.

• Write on the pattern the number printed on the ruler at the starting point. That way you can draw the line in exactly the same place on the matching pattern or in another size.

• Check that the lines meet at a right angle where seams join, for example at center back and the side line.

Common Mistakes

• Drawing curves freehand. The line doesn't repeat itself on the other side or in other sizes.

• Using the sharpest section of the ruler for every line. Choose the section whose curve is closest to the curve of the body.

• Drawing a long line in one go. Draw in sections, and slide the ruler along the line as the curve continues.

How This Ruler Is Different

This is the short, rounded curve in the group, for deep lines: armhole, neckline and sleeve cap. The long 61 cm curve rulers, in metal and in plastic, suit long lines such as the hip line and hem. Pattern drafting usually calls for both types.

All pattern curve rulers are in Curve Rulers. For straight lines and seam allowances see Cutting and Quilting Rulers, and for right angles L-Squares. Before drawing, take measurements with a Measuring Tape.
