Maybe you all knew this already...but I just learned something new! The little post that you push your bobbin into to get it into the wind mode? It is an elliptical shape, and if you loosen the screw and turn the ellipse so the narrowest part is next to the bobbin, you can get a LOT more thread on each bobbin! This has been great for fewer stops and starts with my embroidery machine and with FMQ-ing!! Now why isn't THAT in my owners manual?
