As far as I know Brother thread is made by Robison-Anton. If you have a Brother Disney embroidery machine the color chart is based on Robison-Anton thread. Embroidery thread is 40wt. I have a couple spools of Brother 60wt poly bobbin thread that is made in Japan by Ozeki, maybe bobbin thread is what she was referring to when she said 60wt. I don't use it. I use Coats and Clark poly bobbin at 70 wt and love it, so does my machine. It is the only Coats and Clark thread I use in my machines.
