Eh, again, as someone who has absolutely no artistic or craft skill whatsoever, I would hate the onesie thing and be really embarrassed with what I turned out. I can see that it would be fun for someone who has fine motor skills more proficient than the average second grader, I guess. Bingo is ok, if it's a large group, but then again, I also think it's tacky to invite a large group to a shower.
