I really loved the composition of this photo by Snorkiesnork on Flickr (via oh joy! ). Not sure what the image is from, but the colorful cranes are adorable and seem especially fitting for an outdoor party. I think it's the bright assortment of clothespins that really seals the deal-- regular wooden clothespins wouldn't make half the statement!
I've always loved origami. Cheap decorations, good for killing time in a meeting, and if you happen to get really good at it, you could always try your hand at recreating some of the gorgeous items below. The paper lamp shade and the earrings are my personal favorites, along with the sadly-still-just-a-concept paper crane tea bags. I'd absolutely love to make a quilt out of squares like the ones from Hanna Nyman and Marie Dreiman! Maybe when I retire..
