SINGER machine embroidery needles offer a smooth sewing experience, thanks to the special scarf and enlarged eyes. Design features decrease friction on thread, avoiding shredding and breakage. Needles are sized 90/14, and best used on medium-weight woven fabrics. The set of 5 machine embroidery needles comes in a plastic case that includes sizing on the cover. These needles can be used with SINGER, Brother, Kenmore and other quality sewing machines.
