Hello Kepeters,
My Singer 15K-80 treadle is wonderful for FMQ - you will find loads of information if you visit my blog (link below), and Youtube channel where I have put a video about FMQ on a treadle. My feed dogs don't drop, so I just set the stitch length to zero.
I have turned into a bit of an FMQ addict over the past few months. The hardest part is getting started. After that it just takes practice.
Good luck!
