The first rule of sewing machine needles is: Use a new needle for each project. But you can ensure even better results by choosing the genuine needle designed especially for your kind of project. If you’re sewing on thicker fabric or your doing particularly dense embroidery, we recommend the Janome Red Tip Needles. At size 14, it’s a little thicker than the Blue Tip Needles, giving it extra strength and durability. It features a special flat back shank for easier installation, a sturdy shaft with front groove, and a larger eye to help prevent thread breakage.
