Also, you don't have to take the time to make quilt sandwiches if that is something holding you up. Get a big package of regular 9" x 12" craft felt from the craft store (or online from Amazon). Pin two pieces together to make a "sandwich" and go for it. That gives you really quick materials to work with and they're not precious, so you can concentrate on "playing" with your FMQ. It's a quick and easy way to get better fast and to build some muscle memory for various motifs and patterns you might want to use.
