The bobbin winder that came with my Innova has you put the thread thru the 1st hole up at top, then go down to the bottom but put it thru the right side 1st then the left side before going up to the gear up at the top which also goes thru that gear before taking it back down to where you attach the bobbin to wind it. Think that cross over at the bottom adds more tension to the thread as it winds. I'll see if I can take a photo of what I'm trying to explain as I know I don't explain well.
