Love the Elmo's glue story! You know, if you haven't run into problems with the bias edges pulling all out of shape you're a way better stitcher than this old lady. One of my first large quilts was for son and daughter-in-laws wedding and I did a Daniella Stout pattern. Starched the fabric half to death and I still had bad words echoing out of my sewing den.
Edging around the quilt is called binding and yes you can buy it, usually any store with a sewing section has double fold bias tape in a variety of colors. Navy blue shouldn't be hard to find. Can't think of a tutorial right off, try UTube with search for "binding a quilt".
Or seize the opportunity to go wild and crazy by making your own binding. Don't you still have any old "go to h@ll" shirts from back in the day?
Okay, now I'm going to be banned from QB, Cheers! L'il Chickadee
