Signature thread is a high-quality, low-lint thread that is perfect for machine quilting, whether on a long arm or a home sewing machine. Three-ply, one hundred percent mercerized cotton means superior strength for all your sewing needs. Each spool contains three thousand yards of 40-weight thread. Signature thread is perfect for quilt piecing, long arm quilting, and hand sewing on binding. Signature produces such a nice quality thread that's strong and doesn't shred. You'll be amazed at how much less lint there is compared to other quilting threads! The large cone will allow you to quilt for a long time before running out of thread.
