I want to give a friend of mine a quilt for his graduation gift.?

We have been neighbors with a guy that will graduate next year. I am a pretty good seamstress and I would like to make him a quilt. Do you think that would be a good gift? I also do not know what colors to make it or what kind of fabric prints I should put on it. Should I make it a twin or just a lap blanket? Thank ahead of time for your help!
