French Curve Ruler Set
A handy set of three curved rulers to aid in pattern drafting and manipulation. Each ruler contains a wide variety of curves to help you draft pattern pieces and perform fit adjustments. The clear plastic makes it easy to see markings underneath the ruler while it is laid on your pattern.
This set of rulers contains the three most commonly used French curves (this three, when together, are known as the Burmester set). The rulers measure 13 cm, 17 cm and 32 cm.
