Another thing I have found helpful is Nitrile Gardening gloves to wear while quilting. You can buy them on Amazon for about five dollars. They really help in moving the fabric around.
Do remember to put your feed dogs down (or cover them) when you try free motion quilting. When I was learning I made a practice piece with plain muslin top and back with batting between. It's just a matter of practicing and getting your rhythm.
You can also Google "how to free motion quilt" and you'll be able to pull up some videos and helpful how tos! Just be brave and dive in on some practice pieces!
