I just started using Fireline this evening. I make malas and one of my favorite designs uses some small (6mm) beads that I got from Hobby Lobby that are probably acrylic. The problem is, these small acrylic beads seem to be cutting anything I use so far after only a few days of carrying around the finished piece. It breaks with no warning and I'm left with a mess. I've previously used cord and fishing line and gotten these results so my fingers are crossed now that I've re-built the mala with Fireline. I'm hoping this cuts down on fraying as this seems to have been the problem up to now.
I hope this works for you. What size Fireline did you use? I like to use 8# when I use crystals which have sharp edges and tend to cut most threads.
Someone on this forum, suggested I use a "Bead Reamer", to run a circle around each "Crystal" to smooth the sharp edges. (I don't remember wher I found it) Most LBS would have one,(I think)
It is very Irrating to have a piece come apart. Best of Luck
