Many embroiderers will not attempt to use Metallic Thread. They have been frustrated time and time again with broken threads, broken needles and ruined garments. Finally, Floriani has introduced the perfect metallic embroidery thread designed to be used at high speeds on most machines. The Floriani Premium Metallic Threads are created with a very strong inter core made of polyester. The polyester core is coated with brilliant metallic colors but then it is coated with a special lubricating hardener to prevent the metal from flaking. This special lubricant also allows the Floriani Metallic Thread to flow evenly and without restriction through your machine. Most metallic thread manufacturers will advise users to replace their machine needle with a large eye needle before using their metallic thread, but with Floriani Premium Metallic Thread is not necessary. Use the same needle as used for regular polyester or rayon threads. Floriani Premium Metallic Thread has 880 yards of thread per spool!
