Choose your own adventure is the theme of David Trubridge's Iti Kitset Lampshades. Made out of recyclable polypropylene, these lampshades can be made into different patterns using the same kitset. You can even join different kitsets to make a bigger lampshade. That means you can change your lampshade design every year, or every day, if the fancy (and creativity) strikes you.
