I love Fireline for all my beading/threading needs. It hardly tangles, holds its form, and crystals can't cut through. You never have to worry about accidentally piercing the thread with the needle or having it fray. Highly recommend!
FireLine stringing material
This is the first time I have used FireLine. I really like that it is so flexible and easy to string beads.
Always the best, no fraying and always strong enough for every project.
Frayed easily. Very limited use
