When you cut it, makes sure you leave enough wire to do the ends. After you cut it, or even before you cut it, put a dab of thick CA where it is to be cut or where it has been cut. That will keep it from unravelling until you are ready to finish the the ends, Then cut off the excess with the CA on it. It pays to "Plan ah e a d". (We were advised of that somewhere recently.)
