as I use 4 strands together I will cut a length from the skein, fold it in half then half again, let it twist around each other like it wants to do anyways, then put in a pot of water boil for 15 minutes, hang to dry.
Once dry I roll it up like I would any rope or cordage then stick it in a small bag I have to keep it clean.
I keep the bag and the wire together, with a paper clip, so I know I always have them where I can find them.
