'puffy' is much more forgiving. the stitches sort of bury themselves in those grooves. go with puffy for a while until your confidence increases.
don't be afraid of the bobbin. you're bigger than it is. :mrgreen: whenever you tighten/loosen the bobbin, turn ONLY 1/4 of one revolution or even less, at a time, until you're comfortable doing this. follow roben's advice about keeping notes: whenever you move the bobbin screw, write it down. when you want to return to the original position, you'll know where to go back to.
if you've moved the screw more than once i.e. 'moved to the right 1/4 turn. moved to the right 1/4 turn.' then you know you did it twice, or you moved to the right 1/2 turn total. when you're finished go back 1/2 turn to the left.
am i speaking in tongues? :oops: :oops: :roll:
