Hi
I piece with Aurifil, basically the only thread I use, other than embroidry thread. It is a bit higher cost, but it seems to last and go a long way for the top and bobbin. Also, it is very low lint and is good for my machines, they love it and so does my machine dealer!
I use Guterman (spelling?) cotton if I need a color I don't have in Aurifil as no one around me has the Aurifil in the small spools. For embroidery I use Sulky or Maderia, and also for my applique.
