Ok , picked up some Gutterman (made in Germany) spools of thread since one hears it was one of the better threads. Well am here to tell you after spending almost two days trying to work with the stuff, that simply is not true.
Lint, lint, and more lint! Have wooden spools of thread that make less lint than this polyester Gutermann. My other problem was trying to get the tension correct, which no matter what one did, it just was not happening. Was running up some medium weight canvas as laundry bags (Christmas presents), and no matter where bottom and or top tensions were adjusted to, had nothing but problems.
Needle changes, cleaning tension disks/feed dogs, bobbin case, rethreading, and so froth did not produce any better results. Each time all one got was either a mess of loops on the bottom thread, or upper tension adjusted so tightly to avoid this, thread would break and or fabric would pucker. Finally gave up and went back to pure cotton thread, and viola, problems vanished. Guess my Pfaff just does not like Gutterman thread.
