There is a blogger, Lori Kennedy, who does wonderful step-by-step free-motion quilting tutorials. She has started a series of doodling tutes that people are finding really helpful for building muscle memory and freeing up their creativity. Her blog is The Inbox Jaunt.

She just recorded a Craftsy class that I bought, but I haven't as yet watched. It's getting great reviews.
Check her out.
