Stop in for a cup of coffee

Got a start to installing the hardware cloth (weird name to me) around the garden. Well, started the dirt prep anyway, two passes around the garden with the rototiller, now have to pull back the dirt at the bottom rail. The wire goes two feet up and hog rings to the chain link with the other foot down to be buried so those little rabbits will hurt their little diggers! They've ate the hell out of my green beans, just a single stalk left no leaves. Also got half of my peas, at least we got one picking out of those.
What size mesh and how far underground are you setting it?
