Polyester quilting threads

Polyester quilting threads are a perfect choice if you are looking for strong threads that are relatively invisible. The threads are less likely to show through the fabric.

The thread can be used with both hand-quilting and machine quilting. The thread will also work well with decorative stitches, making it a versatile choice for quilters.

A quilter has to decide what type of stitching they plan to do. If you are hand-quilting, you will want to use polyester thread because the stitches will not show through the fabric. This also will lessen the strain on your hands.

Machine quilters can use polyester thread when sewing the layers of the quilt together. The thread will help when using decorative stitches such as appliqué or embroidery.

For both hand-quilting and machine quilting, it is important to use a needle that is appropriate for the weight of the thread you choose. Polyester is a synthetic material, and it is stronger than cotton threads, so you need a thicker needle in order to avoid breaking the thread. As you can see, there are many benefits to using polyester threads when you are quilting. 

Is polyester thread-safe for quilting?

Yes, polyester threads are one of the best choices for quilting. If you are making quilt blocks, it is one of the best threads to opt for because they help the seam appear flat and do not let it bounce up after stitching. 

Moreover, quilters prefer polyester thread because it is lint-free and does not require the bobbin to clean again and again. It also saves your sewing machine from lint build-up. 

Polyester threads are also safe because of their strength. These threads can retain their strength and make the stitches last longer than the cotton threads. Polyester threads also do not damage your fabric as opposed to earlier beliefs.

Polyester threads come in two variations- cottonized polyester threads and trilobal polyester threads. The name cottonized thread might make you think it is a cotton mixed thread; however, it is not. 

It is a 100% polyester thread and has been treated to take all stretch from the thread. The name cottonized thread is given because of its cotton-like qualities, and it is incredible to sew with.

Trilobal polyester threads are triangular in shape, and these threads have a shiny reflection in them. Both cottonized and trilobal polyester threads that come from quality manufacturers produce zero lint which is extremely good for your sewing machine as well. 

Can I use polyester thread on cotton quilt fabric?

Polyester threads are safe to use on cotton quilt fabric, but the sewing machine needle needs to be changed to accommodate polyester thread.

This is one option for those who want to stitch a quilt with polyester thread. For the first few stitches, the stitch should be set for a heavy-duty stitch and then, as the polyester thread is used, should be set back to a standard stitch.

It is vital to remember that not all machines are compatible with polyester threading. If you are unsure about your machine’s compatibility, do not worry, as there is a solution.

You can use a cover for your sewing machine or buy a cover that is designed to work with polyester threading. Remember to switch the needle every time you change the thread type; this will ensure proper stitch quality.
