yep...sounds like what happened to me a couple weeks ago...the machine was sewing fine one day and not the next! Made me think little elves woke up in the night and messed with it! LOL I rethreaded mine a dozen times to make sure I wasn't doing it wrong cuz thats what it acted like...oh well, it is still on the shelf waiting for a trip to the shop. Nothing I've tried has worked...glad you got yours working again! :-) Wish I could say the same! :(
