Pattye's Heavy Tenara® HTR 138 Cord, Navy Blue Thread, PTFE, Synthetic, Knot, Braid, Crochet, mend outdoor fabric


Shipping to United States: $4.50


Navy Blue Tenara

Heavy Gore-Tex Tenara® HTR 138 thread, which is unaffected by exposure to UV rays, chemicals, salt water, dirt and sweat. This extreme durability and ease of use make Tenara desirable for jewelry applications of stringing, knotting, braiding, crocheting and leather wrapping.

I'm currently experimenting with Tenara, finding that it knots easily, drapes nicely, doesn't fray and has a smooth, slick finish which is easy on the fingers. A whole spool costs about $120-$130, so I'm offering it to you at affordable lengths. Please let me know how you use this in your jewelry designs! I'll be adding photos of my creations soon.

Tenara thread is also used widely in the marine industry for sewing sails and for outdoor upholstery as it is unaffected by UV rays. NASA spacesuits are made of this thread!

    Beautiful quality tenara cord, fast delivery, very pleased. Highly recommend this seller!

    As advertised, high quality thread, reasonable price for smaller quantity I need for repairs to my sailboat sunbrella fabric. Prompt delivery.

    Just what I needed. The perfect weight for what I was creating.

    Thank you for the kind note!! I'm always in search of new strong cords and threads for my jewelry making on my journey learning the craft, and I love this one. It's a beautiful, rich deep navy blue, it knots perfectly. I can't wait to try it on the sapphire beads with tiny holes I've had for years that need a very strong but thin string.
