I know some people who use Maxilock serger thread exclusively. I've used it a few times. What makes serger thread, "serger thread," is that it's only 2 strands of thread twisted together. Our regular sewing and quilting thread has a core of cotton or polyester, with cotton or polyester wrapped around the core. I probably wouldn't use it for a quilt that will be loved to death. But I'll use it for some quilts.
