Aurifil makes poly thread. I have many mini cones of the solid colors before it was changed to variegated. Most think Aurifil makes only cotton thread because that's all the quilt shops sell. Also I have the super big cones of 60wt and 80 wt Aurifil cotton.
I have an old microscope and look at different thread brands under it. I can tell in a glance which brands are smooth, no slubs, not hairy looking. I will definitely look at this thread next to the Aurifil and other brands I like. Lots of good brand thread has thin and thick spots and slubs. I was surprised.
