Is It OK to Use Polyester Thread In a Quilt?

We are often asked, "Is it OK to quilt using polyester thread?"
Our answer: "Absolutely!"
But what about all those stories we hear about polyester cutting the fabric? Not true. If a thread were to ever tear through the fabric, it is because the thread is very strong or abrasive and the fabric is quite weak.
Some cotton threads are stronger than polyester threads so if a thread really were to tear through the fabric, some cotton threads would do this easier than some polyester threads. Think about your 100% cotton t-shirts. Guess what kind of thread they use to sew the seams together? Polyester thread and it DOES NOT tear through the t-shirt. How do we know what kind of thread they use? Bob called them and asked.

So Fine/50 wt./ polyester for quilting and general sewing.

The stories we have heard are myths handed down from grandma's generation when the only available thread was cotton. Cotton thread is great. Polyester thread is great. We like to piece with cotton (MasterPiece) and quilt with many different types of thread.
Here are a few of the facts we have gathered as we have studied the threads of today:
* The seams are the true stress points of a quilt, not the machine quilted area.
* If the fabric ever tears as a result of heavy use, it most likely will tear at the seams.
* Machine quilting does not add stress to the quilt. It strengthens it.
