Despite the mixed reviews this idea got over at ATLA, we think this is a sweet idea to decorate a kid's room or use as a quick, pretty birthday party decoration. And it's so easy that your kids (the ones old enough to be trusted with a needle) can do it themselves.
Veronica of Petunia used mostly cupcake liners and threw in some circles cut from sheet music and patterned paper. String them together and voila!
(You may remember another great project of Veronica's: decoupaged vintage modern chair. She also has an Etsy shop, Petunia's Place.)
