Similar to the tree bookshelf I shared before, these rugs by the artist Alexandra Kehayoglou bring nature into the house (and other indoor spaces). I really like the variety of colors that mimic the visual appearance of the wild fields. As shown in the above room, the rug complements wood furnishings quite well, but I can see it bringing a sense of freshness to a concrete office floor as well. Practically, I see a problem of cleaning this rug as it is composed of numerous pieces, creating an uneven surface possibly hard to vacuum.
