I used to use Fireline - it is a fused fishing line that is easy to thread onto
a needle and the only color I have ever seen it in is black - which worked fine
for everything I made with it. I don't use it anymore though. I use SoftTouch
for lighter pieces and SoftFlex for everything else. It costs more, but I
think it is definitely worth it.
