Before you begin, it's essential to select the appropriate twin needle for your project. Twin needles come in various sizes and widths, from 1.6mm (2.0mm between needles) to 4.0mm (6.0mm between needles), and can have ballpoint or sharp points depending on the fabric type you are sewing. Ballpoint needles are best for stretch fabrics, while sharp needles work well with woven materials.
Before delving into its benefits, it’s important to understand what an automatic bobbin winder does. In traditional sewing machines, winding the bobbin, which is a small spool that holds the thread for the underside of the fabric, can be a tedious process. It often requires precise manual operation to ensure an even wind without tangles. An automatic bobbin winder, on the other hand, takes the guesswork out of winding thread. It automatically stops when the bobbin is full, preventing over-winding, which can lead to knots and an uneven thread tension.
