A tree branch slice coaster is a wonder of simplicity: it's rustic, it's organic, it's functional, and adds some outdoor style to your coffee table. And they're easy to make, costing you much less than buying a set; you just gotta know what you're doing. Mike from Instructables offers his take on the project. He walks you through selecting the right seasoned wood, safely slicing the non-square, natural shape, finishing to prevent them from further cracking, and employing a cool stacking technique that helps the coasters stay organized, looking like a length of limb while not in use.
