Sweet Rose Lampshades
I was in Pottery Barn Kids the other day and saw these sweet lamps. The lampshade alone is $99, though, and the base is $49. I happened to hit Michael's the same afternoon, and when I saw the aisles and aisles of faux flowers, I figured there was a DIY project in it for someone with a good glue gun and a lot of patience.
Or you could try to split the difference -- Home Goods had some similar shades for half the price as the PB one, but when I went back today to snap a picture, they were gone!
