Sally1019, I did serge it. You could use a zigzag stitch with a walking foot and it would work as well. I used as many if the existing seams as possible to minimize the work I had to do and the chance of it unraveling. To prevent unraveling you could use fray-check or something similar, though I just tried not to handle to fabric much after it was cut. Good luck and if you try this just don't stress over it too much. go with the flow.
