I have the older model Tin Lizzie. I use thread from Threadart (online store), it's cheap, all cotton. The only problems with it are that each large cone has a knot in it, it also makes lots of lint which I clean with each bobbin change. I deal with it beacuse it's good thread and cheap. I buy M bobbins, needles and bobbin caseings on ebay, there are many sellers and prices are good. Congratulations on your Lizzie! The fun is just starting !
