C.S. Osborne No. 501½ 2½-Inch Light Curved Needles

When to choose it
Choose this 18-gauge curved round point when you want a compact arc in Osborne’s light series. The 2½-inch size is measured across the entire needle. Use that measurement to see whether the curve can turn next to the seam or seat frame.
If you want the same nominal size in a finer round point, Osborne lists the 2½-inch 501X at 20 gauge. Compare the gauge while keeping the size steady. This box gives you twelve needles in the selected light variant.
