Riprap cap

I need to install window blinds in the kitchen and need to drill small holes in granite tile. What is a proper way of doing it to avoid cracking the tile?

Hi. Thits is my first post. I currently have a thick (6-8"), well compacted gravel driveway. What I want to do is 'cover' it with river rock. I'd like to end up with something that looks like a dry river bed (if that analogy makes sense). I have access to, literally, tons of river rock, much of which is flat sided (at least on one side), and some of it is 'disk'-like. The rock ranges ranges in thickness from a half inch to 2-3 inches, and diameters from cup saucer size to frisbee size. And, of course, it varies in color and texture greatly. Since I am after a very rustic look, I'd like to avoid having too much appearance of being 'set in concrete', and I'm not really concerned with having it as flat as possible (unevenness is ok). In fact, in some spots I wouldn't mind having small outcroppings of rock (in non-traffic areas, of course). Anybody have any advice as far as how to proceed? So far I've experimented with just laying the rock down to check the appearance, and I really do think it looks great. What I need to know is the best method for keeping it 'in place'. And, since I'm sure the question will come up, yes, cars will drive and potentially park on it. Plus, occasional UPS trucks. Oh, almost forgot. A few years ago, at a 'home and garden' show, I saw some form of exposed aggregate that was set (imbedded?) in some kind of clear 'plastic'. Anybody know what that (plastic mortar?) material is called? Thanks in advance for any replies.
