Keep going. Work in sections and stop after each section to look at what you accomplished there. Adjust your tension (in the bobbin case even) if you have to. Roll up the part of the quilt that you are not working on so that it will go through the throat easier. Practice first on small sandwiches like potholder size until you get it where you want it. I don't understand what you mean by using an embroidery stitch and free motion. It is usually one or the other. Hope this helps.
