I was going to suggest that too. One of my guild sisters made a wonderful "window" quilt with a large panel. I have also made a variety of borders and pieced blocks to go with panels.

Hmmm... something other than a quilt, huh? Maybe a seat cover for the car? Padded sun visors? A camera bag? Curtains for the family room?

Here is a sample of how I finished off a panel. It was a wide panel (42") wide and the group wanted to make a quit for a Veterans Home. You might see an idea here to add to your panels in this way or surround the panel. I don't know how to turn the picture.
