A time ago somebody wrote here that it is a help to use the metalthread by taking the design upsidedown. I do not have the problem with breaking thread, if I use the threadholder from designsbysick, it's a really good help, also for the always twisting slippery Rayon and use the lowest speed. But yesterday I made a butterfly and name on a scarf with metal thread and Rayon - the backside is much more gleamy and bright than the front! I will change it now always to use the design upsidedown and put the color I want on the bobbin. Can try it??!!
