Item Description

Tenara® Lifetime Guaranteed Thread features unique PTFE (polytetrafluoroethylene) fiber construction that extends the life of fabric seams and ultimately the products in which it is used. GORE™ Tenara has high strength and durability that for over ten years has proven to be unaffected by exposure to UV rays, cleaning agents, pollution, saltwater, air, rain, and snow.

Great for outdoor, awning, and marine applications, Tenara thread will not rot if left outside all year round. Remains colorfast even in extreme temperatures and frost. Although more expensive, Tenara is a greater value than other polyester threads when considering life span and re-stitching costs. Choose Tenara thread to improve the performance of outdoor fabrics where seam life and integrity are of the utmost importance.

Tenara M1000H is similar in weight to V-138. Heavy Tenara thread requires a needle size of #19 or #20. Smaller needles may cause skipped stitches and/or the double ply thread to unravel above the eye of the needle. Tenara thread does not require as much upper tension as normal polyester thread. Heavy Tenara thread usually requires less tensioning which will result in a good looking stitch on both the top side of the fabric and bottom, but the knot on the bottom side usually does not pull up into the fabric all the way.

Sailrite's Hints for Sewing with Tenara Thread:

If the Heavy Tenara thread separates and bunches up above the eye of the needle or breaks:

  • Try a larger needle size - a #19 needle size is a good place to start
  • Reduce bobbin tension until it pulls from bobbin case with only a slight tug (like pulling dental floss from a container)
  • Reduce upper tension until threads are neat on the bottom of the fabric (knots usually will not be pulled up into the fabric)

After reading many reviews and speaking with Matt Grant I decided to try the T

Tenara heavy clear thread.


After reading all the reviews on line and talking to Matt Grant I decided to order some Tenara heavy thread for exterior canvas projects. I purchased the heavy because the size is close to the standard V 92. Ordered clear and was expecting something like fishing line but was surprised to see a twisted thread. Using it in a commercial Juki machine with a size 19 Serv 7 needle and pulling the thread off the top of the cone. After a few rows of stitching and tightening the tension about two turns it sews just like any other thread. Saws through two lares up to 8 lares with no further adjustment needed. Very happy with the purchase after hearing so many people say it was hard to sew with and skipped stitches. So far no skipped stitches when using straight stitch. Have not tried zig zag yet. Should make my projects last a lot longer in the Arizona sun. It really isn't clear but a milky white. Think I will order the other colors.
