Can i use polyester thread with cotton material for quilt?
If it is a quilt you are making to become an heirloom then you are better off using cotton thread. The thought behind that is that if there is any stress, the thread itself will break before the fabric will tear. It is easier to repair a seam or quilting stitch than it is to repair a tear in the fabric. There are some who even think a poly thread will actually cut the fabric over time. On the other hand if you are making a quilt that will be used and dragged around and generally loved to death, then it doesn’t matter as much. This is one of those questions that will spark discussion where one quilter argues in one direction, another will argue in the other, and the rest of us don’t particularly get too excited about it.
