Choosing the correct upholstery sewing thread for when your project starts with knowing what different options are available. Because, when you realise how many different threads there are out there, then it can get a little bit overwhelming. However, the trick to choosing the right thread is by selecting the right weight, thickness and finish for the task in hand. But, we know that is easier said than done if you are entirely new to the concept of sewing. This is precisely why we have created this article to help you understand the different upholstery sewing threads.

Cotton Thread

Cotton thread is an incredibly soft material which is very absorbent and warm. It’s a very good option if you are looking to sew it with other plant-based materials such as linen or rayon. Cotton is also a brilliant material to dye because of how absorbent it is. However, the downside to cotton is that it doesn’t have any give or take and will break when faced with even a small amount of tension. Therefore, we do not recommend it for stretch fabrics or pieces of clothing like jumpers.

Rayon Thread

Rayon thread is a plant-based material that everyone knows for its vibrant shine. This type of thread is nowhere near as durable polyester, but it is incredibly cheap to buy and is extracted from a renewable resource. Most people that practice upholstery use this type of thread for embroidering. However, we do not recommend that you use it for seaming because of how weak it is to polyester.

Polyester Thread

Polyester thread is a synthetic based material. It’s not very expensive to buy and durable and long lasting. It is able to withstand exposure to moderate heat but doesn’t actually absorb moisture very well. If you are looking for a reliable upholstery supplier where you can buy polyester thread for a good price, then we recommend choosing Heico Direct. They currently have a 10% off promotion running on all their polyester threads.

Nylon Thread

Nylon thread is a synthetic type of fabric that doesn’t shrink and boasts a good amount of elasticity. One thing to be aware of is that nylon melts incredibly easy. So, you should avoid using an iron on it at all costs. However, bonded nylon is brilliant for utility style projects and can be very practical for making things like sports gear or camping equipment.

Silk Thread

Silk thread is one of the finest and strong types of fabric that we are going to cover on this article. It’s a great type of thread to work with whether you are sewing with or without a sewing machine. Although, most people decide to use this thread when sewing because of how smooth it is. If you do decide to sew by hand, then you might find it a little difficult to thread the silk to start with because of how fine it is. However, there are 2 very simple but effective solutions to this. The first one is to make sure that you hold the tail of the thread as you pull the needle through the silk. The second solution is directly tying the thread to the eye of the needle.

Wool

Wool is an animal-based thread obtained from sheep and other animals. The wool can be spun into fine, medium, and thick weights and is produced by follicles, which are small cells located in the skin. Wool is widely used in clothing from knitwear such as socks and jumpers to cloth used for suits and costumes but can also be used in the furniture trade such as chair covers, blankets, horse rugs and saddle cloths.  It’s especially useful when making carpets as it dyes well, creating deep, rich tones. Wool is typically sold by weight, but the price varies so much depending on the quality. The high-quality wool thread is expensive. If you market correctly and sell a consistent quality product, your sheep can pay for themselves by their fleece alone.
