Machine embroidery has two key players—top thread and bobbin thread. Without question, bobbin thread is the unsung hero of machine embroidery! And that’s why it’s so important to not run out. Fortunately, we have lots of options for you to choose from: spools, pre-wound, even Magna-Glides and colors! So whether your preference is to wind your own or pop in a pre-wound, we've got what it takes to keep your bobbin full…and smoothly doing its job.
