Despite not being an outdoorsy person, I love nature but I love it more indoors. I regularly bring home little bits of the outside. On my desk is a tiny bowl of sea urchin shells I painstakingly brought back from a scuba diving trip. In the living room hangs a sculptural (and broken) tree branch I dragged home from the neighborhood park one day. Inspired by the great wilderness, this week’s roundup features home decor with natural elements—all available for sale on Apartment Therapy Marketplace.
