The Houndstooth Collection is a duo-tone textile pattern characterized by broken checks or abstract four-pointed shapes, often in black and white. The repetitive geometric pattern in this mat is a made up of the colors Charcoal and Blue. Mad Mats outdoor mats are made from recycled plastic and are environmentally friendly. This plastic straw like floor mat (think spaghetti) is made from recycled polypropylene and can be used on lawns and patios. The soft tubular threads don't absorb dirt or stains of any kind so the mat won't mildew or rot your wooden decks. Leaves, debris and food spills are easily rinsed away with a garden hose. Mad Mats patterns are intricately woven and the multi colored threads are woven in the same fashion as real flat weave wool rugs. The result is a warmth and complexity usually only available to the interior rug market. You put it down and... that's it!
