Cuties is there anyway to adjust the top thread tension on a Viking Designer 1? Before I go and try to find my books where ever they are!

absolutely, go into you main screen and select 'set' on the top option and then just adjust it with the buttons that show. If it's not 'set' then it's the adjust on the bottom of your screen. Mine is running right now so I can't check it for sure, but it's one of these two. Normally you don't adjust it yourself unless it's a strange fabric combo. Good luck, have fun........
