Long Darning Needles are suitable for all Embroidery techniques where the base fabric is no longer counted. They are particularly popular for Bullion Knots and loop stitches, for woven stitches and trellis, for basting and connecting many layers of fabric. Sizes 14-18 are particularly popular for hand Embroidery. They are the ideal complement to Embroidery Needles when it comes to strong threads, e.g. B. Pearl Cotton 3 and 5 or Soft Cotton.
