French Curve Sets: Available in 3, 4, & 8 Curve Rulers Set

French curve sets are used to produce curved lines through a set of points. They are used in a variety of applications including drafting, graphing & sewing. A series of reference points are plotted. Using the French curves connect the points creating a smooth curved line by matching two or more plot points keeping the small radii of the curve with the small radii of the plotted point. This helps avoid abrupt changes in curvatures of the plotted shape.
