Hm, we have that popcorn crap on the ceiling, so I don't think we could put them up there like you have.

If I was *really* creative, I could shade the thing ... light blue on one end to dark blue on the other, put clouds and rainwbows on one side and stars and moon on the other... nah, that's probably too cutesy.

However, we do have a set of star and moon sheets that Brendan used to use, those could become his... IIRC they're navy and gold on white, and I think we have an adult set around that's white on navy - maybe I decide to sacrifice those for curtains with a tension rod. Although they're t-shirt weight jersey material, not sure they'd have enough drape for curtains. I'm sure we can find appropriately starry fabric for that, though.
