Since your bobbin and top stitch threads can only be seen from the back of a project, there’s no need to color-match them. Some people prefer black or white bobbin thread for a more subtle look.
When stitching, use high-quality materials to make your project last longer and look better. Make sure your practice makes perfect for getting good results every time. No matter what type of stitch you’re using, high-quality materials are always a good idea, regardless of the bobbin thread.
Is It Necessary to Match the Bobbin Thread?
No. The bobbin thread provides enough strength without adding bulk, even though it is lighter than the top thread. Using a cotton top thread with a poly bobbin thread is fine. It is also possible to use a 50 wt cotton bobbin thread with a 30 wt cotton top thread. Use the same thread on top and if the bobbin is fine if you want a reversible design that shows off decorative thread on both sides.
With both top and bottom threads, sewing machines are factory-preset to form even stitches. No adjustments are necessary when the top and bottom threads have the same fiber and weight. It is necessary to adjust tension settings if cotton is stitched over polyester, metallic over poly, or thick thread over the thin thread.
According to this article, using different weighted threads on top and bottom is okay. Different fibers can also be used on top and bottom. As a result, polyester 40 wt is acceptable. The top and bottom threads tugged at each other. The strength of both sides of an identical thread is equal when sewing on the same layer of fabric, resulting in a draw. During sewing, top and bobbin threads must not be visible to ensure perfect even stitches. Let’s discuss this in more detail.
1. About a Color Match:
To avoid problems, use the same color for the bobbin thread as you do for the needle thread when sewing. Furthermore, the thread must match the color of the right side of the fabric.
However, it is only sometimes necessary. Your stitch is not balanced if you use a bobbin thread of different colors, and you can see specks of different colors on your project’s right side. If the bobbin thread does not show on the front, do a sample, adjust the tension, and proceed.
This is different from machine embroidery. There is often a difference in color between the thread in the needle and the thread in the bobbin. Usually, a white pre-wound thread is used in the bobbin, but in some cases, the threads need to match (for example, when doing free-standing lace embroidery).
2. About Fiber Match:
We use the same thread for convenience. However, needle thread and bobbin thread don’t have to be identical in fiber and weight. There is nothing wrong with using a heavier thread in the needle and a thinner thread in the bobbin, cotton thread on top, polyester thread on the bottom, metallic on top, polyester underneath, Etc. When shirring, for example, you may have to use an elastic thread in the bobbin. Adjust the tension for each project, which also depends on the thread. When thread weights differ greatly, birds’ nesting may occur.
FAQs (Frequently Asked Questions)
Does Bobbin Thread Have to Match an Embroidery?
Embroidery thread and bobbin thread can be different colors, but you should ensure that they match or are close to matching each other. On the underside of your embroidery, bobbin thread can sometimes show through.
Can I Use Different Weight Thread in the Bobbin?
We often hear that you must use the same thread on top and in the bobbin. It’s simply not true, and here’s why. To maintain tension, your sewing machine’s top and bottom threads pull against one another.
Color doesn’t have to match the top thread, but you can use whatever color you like. Your bobbin thread must not show through the stitching on top. Only the back of the item will display it. To prevent too much bulk on the back of the item, use a lightweight thread.
