Organ Super Stretch Needles have a medium ballpoint, which is suitable for sewing with simplex, latex, lycra, and generally highly elastic materials. The thickened eye of this needle enlarges the puncture area. The middle ball tip prevents the destruction of fabric threads. A specifically shaped groove reduces the occurrence of missed stitches by optimally spacing the needle from the rotating hook. The loop formation is stable during the entire sewing process. The needle shank developed especially for this needle prevents the needle from "flapping" at high stitch counts. Favorite Uses: Great for sewing on super stretchy fabrics and knits, including knitwear and activewear; using lighter weight threads.
