Great use for a 2x6 Runner: DIY stair runner made from 2.5 rubber backed runners from Costco. Cost approximately $30. So when it gets grungy in a couple years or if my boys ruin it I won't mind ripping it up and laying down a new one.
Stomp Stones are easy to use and install in any surface by just stomping in the ground to create a quick, neat looking pathway or patio area in your outdoor space. Can be found @ Wal-Mart $3.27 by EcoTrend (Recycled Rubber Innovations)
