I was not looking forward to putting extra texsolv heddles on my Ashford loom as the last time I put some on a loom it was on 24 shafts and it took a very long time.
As one tends do do nowadays when pondering on a problem, I did a google and came to this site, http://www.earthguild.com/products/weaving/texhed/rtexhed.htm, and it all become clear. You do not take off the ties on the bundles of heddles until after you have put them on the harness, so they all go on at once in three simple steps! I have been cutting the ties and putting them on one by one! Oh wa ta na Siam!
