When it comes to sewing with a double needle, there are a few essential tips to keep in mind. First, it's crucial to use the right needle size and type. Typically, a 75/11 or 90/14 ballpoint double needle is recommended for sewing knits, as it helps prevent fabric damage. Additionally, you’ll need to select a thread that is suitable for the type of fabric you’re working with, which often means using a polyester or nylon thread for its strength and stretchability.

The material of lock stitch sewing machine needles is another factor to consider. Most needles are made from high-quality steel, often coated with chrome or nickel to enhance durability and reduce friction. These coatings enable smoother sewing, especially when working with dense or heavy materials. Using the right needle material can significantly impact the lifespan of both the needle and the sewing machine, as well as reduce the likelihood of needle breakage, hence preventing potentially costly machine repairs.
