This thread has a perfect twist which allows it to gently coat the edge of wool appliqué, melting into the wool. The result is an almost invisible whipstitch which creates a smooth, clean edge prepared for embellishing. Ellana™ is fray resistant and contains significantly less fuzz, rendering an unparalleled smoothness. Its soft loft is ideal for creating delicate detail when used for hand embroidery. 70 yard spools.
