Frequently Asked Questions


General Information


What does thread weight signify?
It can be confusing, but the higher the number the finer the thread. Likewise, the lower the number, the heavier or thicker the thread. Knowing thread weight is important because the weight will dictate how a thread will appear on your project. 
  • For general sewing including making apparel or piecing a quilt, we recommend a 50 weight thread.
  • For longarm quilting, we like a 40 weight thread so the thread is a little more visible. Most embroidery threads are also 40 weight.
  • For detail work like microquilting or applique we use a finer thread, usually 100 weight.
  • For our bobbin, we prefer a thinner thread, usually 60 weight or 80 weight.
  • For hand sewing and adding decorative elements to apparel we like a thicker thread, usually 12 weight.
These are basic guidelines and are directional for your information. Experiment with different thread weights and materials (polyester, cotton, etc.) to see what you like best!

What is the difference between polyester and cotton thread?
Cotton is a natural fiber, and therefore cotton thread is a natural fabric. It offers rich color in a matte finish that often offers a subtle appearance on quilts. Cotton thread doesn't have any stretch, which is why it is often preferred by quilters. 

Polyester thread is a synthetic fiber. It is known for being very strong and therefore can be made in thinner weights but still maintain its strength. This allows you to use thread that will be very fine on your project. Trilobal polyester threads offer great color and can be manufactured to have a beautiful sheen to them. 

It is a myth that you can't use polyester threads for quilting, or that the thread will harm your quilt. The polyester threads we sell at OneStopThreadShop.com are safe, appropriate and desirable for quilting.


Thread Help


Why is my thread shredding on my longarm?
One of the most frequent reasons that thread shreds is because the eye of the needle is too small for the weight of the thread. If your thread is shredding try using the next size larger needle. 

Why is my thread so linty?
Lint is caused by the tension of thread and fabric rubbing together and is a fact of life in sewing. If longarm quilting, make sure your quilt is not loaded to tightly on your frame as that can increase lint. For general sewing, clean your bobbin area frequently to ensure you don't sew lint into your projects. If lint is really bothering you, try a gassed or singed thread like PIMA cotton or Aurifil which is known to have minimal lint.
