Discover the exquisite range of YLI Metallic Threads, manufactured in Japan on convenient 500yd spools. Designed for high-speed embroidery machines, these threads are also perfectly suited to machine quilting, longarm quilting, and hand applications. For machine use, we recommend a metallic needle (80/12 or 90/14), along with reduced upper tension and a soft cotton thread in the bobbin for best results.
