Nice haul! Muv has a lot of videos about using the long bobbin - you will enjoy her info a lot more than my feeble attempts. Look on the sticky about cleaning - there are more links to her info.

ALSO be sure to read her blog - there is a lot of info on there, too. I'm sure you will love that machine. Looks like some sail maker needles. The machine takes regular needles. You are going to have way too much fun!
