Hi! I have the Viking MegaQuilter 18x8, which is really the same thing as a Tin Lizzie, even though mine is not the sit-down version. Where are you located in NC? I live in SC, but work in Charlotte, so if you're anywhere between Charlotte and Gaffney, I'll be happy to meet up with you and try to help out.
BTW, I LOVE my VMQ18x8!!!
