I have a cinderblock wall, L-shaped. Two blocks high, three long, one block on the L. I've been looking for something to top it. These are old-style cinderblocks, not the modern straight rectangle ones, and the top is not quite level.

I found some marble floor tiles discounted to $1.50 each, and bought a carton of five. They are 12x12, so won't quite cover the stretch unless I get them trimmed. I may just cover what I can and use a planter to hide the uncovered part.

Marble can't be left out in the winter, so whatever I do will need to be removable so I can bring it inside.

We're having ceramic tile laid in our kitchen, if there is any leftover base from that, will that work outside? Has anyone else tried something similar?
