Eloflex is a new, innovative thread from Coats & Clark that sews, soft, secure, stretchable seams in knit fabrics. Eloflex is perfect for knit fabrics used in athleisure, cosplay costumes, swim suits, lingerie, and dance wear. Use with knits, but also with fabrics like stretch denim or twill. Use for sewing your own knit garments or for repairs or alterations. Have you ever tried to hem a knit skirt or T-shirt only to have it look stretched-out or wavy? Eloflex will make this a thing of the past. Repairing a popped seam? Stitch it with Eloflex and the thread will stretch with the garment instead of breaking.
