Use wax (beeswax or microcrystalline wax) or a thread conditioner (like Thread Heaven or Thread Magic), to condition nylon beading thread and Fireline. Wax smooths nylon fibers and adds tackiness that will stiffen your beadwork slightly. Conditioners add a static charge that causes the thread to repel itself, so don’t use it with doubled thread. All conditioners help thread resist wear. To condition nylon thread, first stretch it to remove the curl (you don’t need to stretch Fireline). Place the thread or Fireline on top of the conditioner, hold it in place with your thumb or finger, and pull the thread through the conditioner.
