Features 5

  • FIRELINE: This is a microfused, braided bead thread consisting of Dyneema, a gel-spun polyethylene which is known as the strongest fiber, per diameter, ever created. It has an unbelievably high tensile strength and has been recommended in numerous how-to articles on beadworking.
  • DETAILS: Made in the USA, our Fireline is 4lb. test and comes in a smoke grey color. The cord measures 125 yards and .005 (.12mm) in diameter.
  • EASY FINISH: Because this is a super strong material, we recommend using sharp, precise scissors for cutting the string. However, the thread can also be burned instead of snipping. A thread burner is easier to use and more precise. This method seals the ends, which prevents frayed edges or split ends.
  • VERSATILE: Originally used by fisherman as a high-quality fishing line, this thread took off in the jewelry making world. It can be threaded on a needle and used for stringing or bead weaving. The thread does not stretch, or tangle and the strength of the cord is essential when working with heavier beads and findings.

Strong and small
Size: 4lb, .005”, 50 yard Color: Crystal
Really strong! I had to pinch it to fit through a needle but then it worked great. It’s thin enough to go through beads multiple times. I really like it! Will likely purchase again

Awesome thread, but where’s the clip? Awesome thread, but where’s the clip?
Size: 6lb, .006”, 50 yard Color: Smoke Grey
I’ve been beading for several years but this is my first time with FireLine. (I have always used Wildfire) This is quite different, which was expected with it also being sold as fishing line. I think I’m going to really like it. I’ve always stayed away from fishing line; I can’t stand that stuff! But this is very different. It doesn’t tangle like regular fishing line and holds its shape when you curve or bend it. It has a smooth feel and is quite strong. It is just stiff enough to pick up a few small beads without a needle. The color says smoke, but if you look at my pics, compared to white beads it looks black to me. I ordered a 50 yard roll of 0.006 but received a 55 yard roll of 0.008. I’m not too concerned about the size though. Again looking at my pics, you can see that a 2 mm bead will easily take multiple passes. All in all I think it will be an awesome thread to work with, not as a replacement to Wildfire, but as another choice in my bead toolbox. This may seem trivial to some, but I dropped one star because to secure the spool you only get a sticker instead of the plastic clip like Wildfire has. I will have to dig around for a spare clip, because there’s no way that sticker is going to hold. If it weren’t for that small annoyance this would be a 5 star product. ... show more
