This is my favorite tool for beading. This tool melts threads that are nylon based. It works wonderfully on Fireline. I also use it for my warp threads when making a loom bracelet. (Waxed Nylon, not waxed cotton or linen)
Easily zap those pesky, frayed threads with Ultra Thread Zap Tool. This handy tool features a retractable tip and an ergonomic compact design for complete ease of use. This tool will heat instantly to trim, burn, or melt thread for an unbeatable jewelry creation!
