Elmer's School Glue is the BEST thing to happen to sewing/quilting ever! You need to put dots or a very thin line of glue where you want on the bottom piece of fabric and then place the top fabric on it. Then iron it with a hot iron. It stays like magic and after you are finished sewing/quilting you just wash the piece and the glue goes away. I have read that some even water the glue down a bit and use it as a spray adhesive for larger pieces. Have to give that a try!
