good ideas, thanx guys, will try that.
dc: i underlay 6 threads of b50 - 3 for each strand. therefore you have to separate and untwist the string where the serving is going to be. then i put in the additional threads and retwist. if you put enough wax all holds together well for serving.
badgers method seems easier do do. simsons i have to take a closer look also.
cheers
