These cute little iPhone cases are made from nothing more than paper napkins and a little bit of lacquer. Using a technique called decoupage, these cases are made by hand in Thailand and sold on Etsy under the NapPage brand.
What I love about them is that the whimsical designs are fashioned into such clean, professionally finished cases.
Decoupage consists mostly of wrapping the object with paper and then lacquering or varnishing it. You build up strength by using layers, and end up with a rather tough object. Guitarists who break a thumbnail will be familiar with the process — a quick fix for a busted nail is to layer up superglue and tissue paper on top.
You could quite easily make one of these cases yourself (although you may want to wrap your iPhone in Glad Wrap first), but at $20, and with such a great assortment of designs, you may as well just buy one from the Etsy store. They are available for both the iPhone 4 and iPhone 4S, with slightly different openings for the mute switch.
