Quilted Microfiber
Painting my son's room? Suggestions please?

We are moving somewhere new and have been given permission to paint the rooms however we want. I want suggestions on my son's room. He's 17 months old and has cheery wood furnature and his room has a castle and Harry Potter theme. I want to do a cloud ceiling, what about the walls? His quilt on his bed is maroon and navy stripes and soft gray microfiber on the reverse, and his curtains are blue too, with sparlke stars, but I don't want too much blue.

I thought this was neat...

Design A Hogwarts Castle Themed Room
Paint the walls, or just one feature wall, with a grey brick/stonework pattern to imitate castle walls. Add sconces and torch likee lights, paint the ceiling to look like the night sky and hang Gryffindor, Slytherin, Ravenclaw and Hufflepuff banners on the walls. Paintings similar to those that lined the walls at Hogwarts can be hung on the walls as well; or for a fun trompe l'oeil, paint a mural that features a fake window, through which the Whomping Willow or another feature of the Hogwarts grounds can be seen.
