The thing with FMQ is that it's one of those things that requires practice, and a lot of it. It isn't a technique that you can learn and just go do. More like learning to play an instrument - you start out pretty bad and just keep at it.
The class I took suggested using 12" sandwiches and just sewing on at least one of those every day. Many people who are successful at FMQ find that if they've not done it in a bit, they still have to do some "warm-ups".
