Woolly Pocket Living Walls sound cuddly, but they are actually "flexible, breathable, and modular gardening containers." Built-in moisture barriers prevent drips or condensation from damaging the interior of your home, and these Pockets are durable enough for outdoor use, since they are made of 100% recycled plastic water bottles. An added bonus is that they fold flat when not in use, so they are easy to transport if you move often.
