I'll gladly pay the dollar each for the bobbins from now on. How many do I need, anyway? I have 5 of the new ones and one old one that came in the machine. Should I go and buy more, 'just in case'?
Another dumb question. My 99 has a knob that makes the stitch length longer and shorter. Now which way do I need to turn it to make it longer? Anyone know? And how far to make much of a difference in the stitch length? There are no numbers on either it nor on the tension, but on the tension I never know which way to turn it to make it work right, but have gotten it adjusted so it is right at the moment, so won't fiddle with that until I need to.
Thanks for the help.
