This decorative holographic thread is very versatile. Holographic thread is a thinly sliced decorative film that gives the appearance of liquid light. For an incomparable sparkle. It is suited for machine and hand embroidery, embellishing, quilting, appliqué, topstitching, serging, blend-in knitting, scrapbooking and more. Adds sparkle and dimension to any project. A top stitch 14/90 needle is recommended for free motion and metallic 14 for embroidery. We also suggest the holographic to be used in conjunction with at least a 60wt fine bobbin thread.
