Thanks for all the wonderful advice!! I asked my son, and he actually ended up choosing a new quilt block that I have been anxious to try - a vintage Bear Paw in blues. What I've decided to do is set the other one aside (it's camo and kinda 'blah' colors), and work on his Bear Paw first since I'm excited about it. Then when I'm finished go back to the other one and make a small couch quilt for him that he could take to friends houses for sleepovers.
I appreciate the comments that make me feel less guilty about setting it aside now - even for only a season.
