I have always used cotton thread to both piece and machine quilt, however, my stash is slowly dieing and I'm in need to quilt a baby quilt I'm just about finished. My question is: can you use polyester thread (embroidery) to machine quilt? I have only used either Aurafil or Mettler thread, and do not have access to any at this time, so, that is why I'm questioning using the Mettler Polyester!
