Congratulations! to your son first of all. Of course you can always go with a traditional block pattern fashioned like a barn quilt. That always works and should not be difficult to make. A more contemporary design may be a bit more of a challenge but still exciting. What ever you decide be sure it works with carpet or flooring of the room and other décor of the room. I love a nice size wall hanging but not to big in my office space when I was still working. No more than 36"x36". You don't want it to overwhelm the space. I am guessing this would be a good size space considering the promotion. Keep us posted on what you decide.
