Organ Microtex Needles have a slim, sharp tip, which is suitable for sewing with fine materials such as batiste, chiffon, organdy, lace, linen, and similar microfibers. The slender, sharp tip reduces puncture resistance as the needle penetrates the material, preventing needle and thread breakage. Highly compacted material is thus protected against wrinkling. Favorite Uses: Great for microfabrics, silk and lace. Perfect for Sulky Polyester Invisible threads and 60 wt. Polylite. Stronger, sharper and less likely to break under stress. Needle Point: Slim Sharp Point Needle Style: Machine Needle Type: Microtex
