I read articles, practiced on small pieces, watched videos, practiced on a few more small things, meandered through a few baby quilts... It wasn't until I FMQd a large appliqued wall hanging with a lot of areas to quilt that I really GOT it. There was no way out of that but through, and ever since my FMQ has been hugely improved. Something finally clicked.
So that is my advice: when you've hit the wall, commit to something big that has already taken a lot of time and effort to create. If you need the pressure, that will do it.
