What you need:
A cup/glass (whatever size you need to make a circle however big you want your flower to be.)
Sheets of colored paper (can use scrapbook paper)
Take your paper and stack 3 or 4 sheets together. Next, draw how ever many circles can fit on one sheet and cut out your circles. Repeat until you have as many circles as you need. When you have the amount you need you can do a pattern with the colors or however you want and cut a slit in the middle so the light can be put through the paper. Once you have all the circles cut, take your lights and a circle and put the light through the circle and fold up (pinching the bottom so that's the only thing creased) into four sides. Continue until you've used all the lights and circles.
Viola, finished product. A cute and cheap way to get a new look for your room.
