C.S. Osborne K-4 Curved Three-Square-Point Needle Card

When to choose it
Choose the K-4 when the material you are sewing calls for a curved three-square point and you need to compare several arcs. The card runs from three to six inches. It gives you a way to change reach from one part of the repair to another while staying in the same point family.
The point matters separately from the arc. Compare the Dritz curved assortment or a documented Osborne round-point card if the material does not call for this cutting profile. Verify the contents of the selected single card when comparing it with Osborne’s wholesale box.
