The Bottom Line

  • Available in 2 colors, clear and smoke.
  • Use MonoPoly for invisible appliqué, quilting, bobbins, and apparel.
  • Reduced-sheen invisible thread.
  • .004" (.1mm) in diameter (90 denier) = Very fine thread.
  • Iron and dryer safe (medium heat).
  • Will not become brittle over time (nylon monofilament thread tends to go brittle).
  • Will not discolor (nylon monofilament thread tends to "yellow" over time).
  • Strong with low stretch
  • Soft & pliable
