I'm really pleased to find this thread. Starting FMQ is one of my projects for 2012 - I hope to get to it before December. I have just cleaned up my 15K treadle and had a quick test run last week - just a few little squirls. It is a 1945 machine and the feed dogs do not drop. However it works just as well if you set the stitch length to zero.
Can we keep this thread going to show each other our work and pass on tips? I'm not going to attempt anything more ambitious than a mobile phone cosy, and whether it turns out well or a complete dog's dinner I'd like to post pictures so you can all encourage me!
