WhisperTouch
A monster spool of nylon monofilament! Available in two thicknesses—.005" and .006"—in the color smoke. Use it for stitch-in-the-ditch, machine applique, and T-shirt quilts. The thicker sizes make it plenty strong for longarm quilting, yet it is still so thin (and transparent) that you can barely see it. And the large spools go a long, long way.
