What I did today...threaded the bobbin on my Free and Singer and sewed w/both of them!!! Had to adjust the tension on both but I think I got it finally. I do not have a belt for the Free yet so I was just turning the wheel by hand, everything moves so nicely on both of these. I am going to look at Billy's tutorial because the bobbin winder on the Free is gunky and barely moves. I am excited to try and actually sew something w/one of them now. BTW, the singer is a hand crank, my boys think it is great fun to do the cranking for me, lol.
Those shuttles can be hard to thread too.
