TanCalGal These look nice

Kevin Wild - IBB Designer I love the look of a clean valance.

standinginline Based on what I can see of your room I would go with a lace shade--maybe a type of tie window shade that is internally mounted. You can get an idea of photos by searching "tie window shade lace" in google images.

tammylottero I like the idea of something white, possibly with a ruffle and pulled back. You could use something old looking like a pull down shade to block out the light at night. Maybe like this: Bedroom 3 or Master Bedroom
I really like the room! The sheets seem light enough that they might look great. :)

jgreenholtz thanks everyone for your suggestions!

Maureen Randall This room is lovely, I would get faux wooden shades in cream and get shabby curtains for the window.
