Kat on Christmas lights:

• put them up to border the top of your room
• put them around a window or anything else cool
• use pushpins to put them on the wall... there are two wires that aren't connected on them and you can pull them apart and put them on the middle of the pushpin
• Christmas lights are widely available in different colors and stuff around... Christmas! There was a huge selection at target last year!
• dont put them near anything flammable like curtains and dont leave them on 24/7!
