The second idea is lap quilting using either a hoop or the special presser foot with the loop used for quilting and applique work, I found one of these presser foots at my quilt shop and the other on ebay.

In my guild is a lady who has taught us to do hidden ties. You get a very long needle and you go about 4 inches between the layers, bring up the needle and do 2 loops through all the layers and then go another 4 inches between and up to do another 2 loops and continue.
Another suggestion is to do big stitch quilting on your quilt in meander or whatever you choose patterns.
