This is my absolute favorite monofilament thread! I use it as my top thread on so many quilts. Flannel, wool applique, cotton applique, you name it! It is incredibly durable. Will not melt from an hot iron or in the washer and dryer. It has a very slight sheen, almost matte so it blends beautifully. I stitch in the ditch and free-motion quilt with it. I typically match the bobbin thread to either my backing or quilt top. Just loosen your top thread a bit when quilting
