C.S. Osborne No. 501 Heavy Curved Round Point Needles
C.S. Osborne No. 501 heavy curved round point needles are built for thick upholstery fabric, webbing, burlap, and mattress work, where a sturdier needle holds its shape under heavy thread. Lengths run from 2" to 10", stepping from 17 gauge to a heavier 13 gauge as the needles get longer. See Light and Extra Light Curved Round Point Needles for finer fabrics.
