can you perhaps use regular scotch tape to tape posters up on the wall? Maybe buy those projecting light devices that shoot patterns like stars, dots ets onto the wall
I'm starting school in less then a month and I want to make my bedroom look better, I have plain brown furniture (bed, night stand, desk and dresser) a pink chair and blankets/pillow things that don't match, my walls are white and my floor is green carpets, my mom won't let me paint or put holes in her walls or let me change the curtains and wall liner things that have pink and purple flowers on it. How can I make it look cool and more teen-ish without putting holes in the walls, painting or spending too much money?
