I really like the hand-woven outdoor rugs from Harbour Outdoor of Australia. Very ecological as well. The fibers are made from one hundred percent recycled plastic bottles, and they are hand-woven by artisans in India.
Check out the Harbour website here, download their catalogue, and if you scroll to near the end, you'll come across the accessories, including all the rugs. There are quite a few options for patterned rugs, as well as solid colors. Rugged and perfect for outdoor areas.
And don't forget to check out their terrific furniture collections. (More on those at a later time).
