I did a search for you and found a really useful site:
http://www.singer-featherweight.com/ and one of the tips he states, and I use and teach my pupils to do is to use a "thread catcher"
Q: How can I avoid thread jams around the bobbin area?
A: Best prevention is to use a 'thread catcher' or 'anchor cloth'. It is called by different names. It is just the practice of always running off onto a scrap of cloth when you finish a seam and then start the next seam from the scrap. The practice saves thread as well as frustration. It takes a little while to get used to always running off onto the scrap but well worth the effort."
This page tells you all about them, and how useful they are!
