Around the edges? Safety pin the edges to keep the edges in place. If more is coming loose than just the edges, you may want to add safety pins throughout the body of the quilt. Just be careful and remove pins as you quilt. I ruined an expensive walking foot when a safety pin got caught by the foot; didn't notice until it was too late -- the spring in the foot was already pulled out of whack.

For a first-time quilter, the easiest thing to do is to use a walking foot (helps keep the layers from shifting) and quilt wavy lines. This is ***much, much, much*** easier than trying to do straight lines or stitch-in-the ditch and any "mistakes" simply aren't mistakes. With a walking foot you sew with the feed dogs up (normal) and presser foot down (normal). Start at one edge of the quilt and sew across to the other edge, using your hands to gently guide the quilt left and right to make large, soft, wavy lines. Here are some photos of what it looks like when you are done:
