Yesterday one of the first pair of earrings I ever made broke. My brown set. They do pull on my jacket sometimes and that's exactly what happened when they broke. The place where they loop through the ear wire broke.
They lasted about a year but I need them to last longer of course. I'm going to try Fireline instead of Nymo on the next pair. I've heard it can get twisty so you have to be sure to straighten it. I'll cut apart the brown pair and keep all the beads.
