If I am using any thread with poly in it the static this time of year can be miserable... the thread just wants to jump and stay on everything else but where it supposed to be. It helps if I take the thread I am going to use and lay a damp ( emphasis on damp) washcloth around the thread for a few hours before using.. It helps alot... I use big cones of thread and this time of year I even use some damp batting scraps and wrap before shutting down for the night..next day all is well.
