I am in awe of Robin Barcus' fashion/art. In her series called "State of Dress," Robin creates unusual dresses from natural ingredients: lily pad, dandelion (see above), corn husk, pinecones.
Here's a video clip on how she made the "Willow Creek Dress" (2006) at the Jentel Artist Residency in Banner, Wyoming (fun starts at: 1:15)
