Decorate for the day sleeper

If you work third shift and need to sleep. The question is: How do you keep the room dark? This room was to much to paint and yet needed color. This family love dark colors of blue, browns, green, black. So I hand made her blanket by crocheting a granny square in tan with little spot of red, black and blue. Trim half way is dark brown and trimmed at end black. I started looking for curtains till I dropped. I tried all kinds of material and it didn't go with this bedroom. Then I found some material I never would dream to get. These curtains are tapestry. What awesome design and color in it. I just could not resist. Material is expansive but worth the sleep. The room looks awesome and they love it. Easy to clean. Just vacuum the material. Price $200 for curtains material.
