My daughter Bailey's room was fun to decorate. When we started the makeover it was to move out her sister so that she could have her own room. My budget was very tight yet I was able to accomplish this for about $300.
Bailey LOVES the color pink. But I can only handle so much of it. Therefore, I had to keep her away from the room as I started with the paint. The ceilings in here are 12 feet tall, so painting in its self was challenging. I went with a bright green through out the majority of the room and accented the entry way wall and the back wall with the bright pink. It almost looks red depending on the time of day.
The furniture is mostly all from my husband's grandmothers estate. She had passed away recently so I took a mis-matched bedroom group and painted it all white. The bed is an older style bed with spindles, so I painted the balls and spindles the same pink as the walls. The hardware was replaced with updated matte black pulls.
Because the colors are already all so bright I went with simple and plain white letters for her name and used mismatched black and white pattern ribbons. I don't like everything to match. So you will notice that the black and white patterns are all different. The bulletin board was made with a left over canvas and the remaining ribbons.
Bailey, REALLY wanted this circle pattern comforter set from Target. But it was a bit more pricey than I wanted to spend, but in the end I couldn't agree more with her choice. As you see the curtain is another black and white. The corner shelf unit was also from the estate and was in pretty bad shape and dated until I added the white and bright pink paint. The dresser was my sister's when she was a child and has been repainted a couple of times since my kid's have been around. I went with the ovals behind the hardware because regardless of how much I sanded down the wood I couldn't get the old hardware's indentions out.
So that's her room. I re-did all of the kid's rooms since then and hope to share those as well. Hopefully, you will have gotten some sort of ideas from this.
My dad helped me to make this really awesome ribbon holder. I HATE dowels going through my ribbon because if I want to organize by color and I add new ribbon then I have to take ALL of the other ribbon spools off and start from scratch. This holder has a lip on the edge of each shelf to prevent my ribbon from rolling off. I spray painted it black, and then stapled black poster board to the back. 
I bought the black desk and book shelf and lined the back side of the desk with fabric and paint so that the unfinished edges wouldn't show. The storage furniture in the back I got on clearance, and is actually closet organization furniture. The shelves actually slide out. I like that a lot.
