It would be easier with a larger harp, but you can still FMQ with the machine you have. You will need to roll up the area that is to the right of where you are quilting, so that it takes up as little of your 7" as possible. It will be difficult to do FMQ on very large pieces. I would suggest at first trying to do blocks using a quilt as you go technique and then attach the blocks together after being quilted (there are a number of ways to attached quilted blocks...do a search when you get to that point). Once you are very comfortable with FMQ on blocks, then try your larger pieces like a lap or baby quilt.
