Buy it! Your machine may love it or not but at that price it can be used for whip stitching, basting and many other uses. I use poly thread for piecing and quilting. All vintage quilts have cotton thread used in making them because that's all there was to use other then silk and silk was too expensive or impossible to get for most quilters. It's not true any more. Poly thread is great in the bobbin as it is lint free. Masterpiece and Sew Fine thread is all poly as is other top brand names of quilting thread.
