I started out building the Rustic x-End Table but got frustrated with the Xs not fitting well so I left them off. I showed the unfinished table to a friend and she wanted it, but with some changes and additions that lets her use it outside near her pool. So the pics show the final result including the K she wanted in the center of the shelf.
I lined the shelf with glass tiles and a wooden K and grouted everything in. The glass tiles have a few of the blue and green hues you find in swimming pools, I hope.
The top is not glued down just in case the top boards begin to warp or crack and can be repaired. Of course at Restoration Hardware a warp, crack or knot just raises the price.
