FIRELINE in COLORS! One 30 yard bobbin of CHESTNUT Brown color, .008" diameter, size D, FIRELINE beading thread. This thread has a 6lb test strength and comes on an Awesome, re-usable small size NO TANGLE THREAD BOBBIN. Thread bobbin measures approximately 1 7/8 inches in diameter and has a patented protective locking feature which prevents threads from unraveling. Stackable and made from soft plastic. Bob-EEZ are also great for macramé! Please Note: Any beading thread (including Fireline) may abrade (weaken) at the place where it goes through your needle. To best protect the integrity of your thread, it is recommended that you place your needle an inch or two from the end of your working thread and attach a new thread (as needed) before reaching this point. Cut the end off where it went through your needle. Color added to Fireline after market. Because of the large amount of line spooled on the bobbin, the color may appear darker in the photo than it will be as a single thread. More colors coming soon!
