But how do you decide how much bobbin tension to start with? The novices among us might like a few hints on this….presumably the answer is different if you’re sewing two panels of light sailcloth together vs sewing corner-patches on the sail, or stitching a leather bridle for a horse.Jeet (born Jeetendra Madnani on 30 November 1978) is an Indian Bengali film actor, producer and television presenter. The usual instructions tell you how, once the bobbin tension is set, to adjust the upper tension to bury the knot. For any given thread, you can adjust the upper and lower tension to both be high or both be low, and the “knot” will still form mid-fabric. In fact, I’d love to see some general discussion of thread tension in one of these videos. Do heavier threads require more tension? Will the thicker thread, stuck beneath the same spring in the bobbin, automatically end up with more tension than a thin one would? If so, will the bobbin tension still need adjusting? Up or down? When you said “The tension on your sewing machine will need adjusting when you switch thread weights,” itd be great if you could add a hint about HOW it needs adjusting. Download her chart here! Thanks for sharing this with all of us, Sue. It includes thread sizes and also tensile strength, weight, and diameter. Find the perfect size thread for your next project at Update (): One of our readers, Sue L., sent in a Thread Size Cross Reference Chart that she put together to assist her with her work in the textile industry. If you’d like to learn more about thread, check out our post on thread applications, Thread: From Outdoor to Home Décor, or see our Thread & Needle Recommendation Chart. Try to use a needle where the eye is 40% larger than the thickness of the thread.The tension on your sewing machine will need adjusting when you switch thread weights.Thread tends to get stronger as it gets heavier.If another weight is given for thread (like ounces), it refers to the amount of thread on the spool.
Tex (T): Tex is the most consistent of the measuring methods. The higher the weight, the finer the thread. If 1 gram is 30 meters long, for example, then it is 30 Weight thread. It is determined by measuring the length of 1 gram of thread. Weight (Wt): Weight is measured by a fixed weight system. There are many different methods of measuring thread size, and different countries and industries use different units of measure. When you go to compare the size of two different threads, you’ll want to make sure you’re comparing apples to apples. We’re going to decode thread sizes and show you what each one means and how they compare with one another. Getting the proper thickness affects the strength, diameter, sewing machine used, and visibility. Have you ever wondered what the letters in thread sizes stood for? Or why some threads are sized differently? The thread size tells you the thickness of a thread.
