Prewound bobbins have grown in popularity over the past several years. The convenience of not having to wind your own bobbins is what makes prewound bobbins so valuable. A typical prewound bobbin will have between 20% - 40% more thread content compared to a self-wound bobbin. This is because prewound bobbins are wound with advanced machinery at a high rate of speed.
Most quilters and sewists prefer to match the color of their bobbin thread to their top thread. This is not necessary, but can help avoid obvious signs of uneven tension. Because the color of both threads are the same, it's difficult to notice if the top tension is too tight, resulting in pulling the bobbin thread up. Using a neutral-colored bobbin thread is also a popular choice, especially when using blending fabrics.
