I'm with you about learning FMQ. I have been dabbling for quite awhile and find it challenging yet fun. One thing that made me feel good is to realize with a little practice, I can actually see improvement in my attempts. Definitely not there yet, but keep plugging along.
I have loved the Craftsy FMQ classes. They do make it look easy but they also have good tips. My favorites are Leah Day, Angela Walters, Christina Carmeli, Lori Kennedy. I also liked Cindy Needham's class. Each of the classes have FMQ designs that I print off, insert into a plastic paper protector and use a dry erase marker to go over the lines. It helps with the doodling. I also have the notebook to doodle on my own. Just some of the ways I'm trying to learn FMC. Of course, the best way is just to do it :-)
Good luck with your learning curve. Keep at it.
