It's a miserable, awful medium to work with. For installing it, I find a staple gun makes your life much easier. It isn't a permanent/long term solution but acts as a temporary glue. Lots of people recommend screws with washers. I like a furring strip (1x2 or 1x3 or 1x4 piece of flimsy wood) with nails or screws. For smaller operations like a window, make a wood frame in two layers. Lay it on the first frame, then screw the other frame making an HC sandwich. Cutting Hardware cloth: Tin Snips and Wire cutters work, sort of but its tedious and you invariably end up bleeding. This is what I've found works well. An Angle grinder. Circular saw. Probably not good for the blade but I don't care. A Dremel with a metal cutting wheel or cutting wheel. You can buy a cheap Walmart brand rotary tool for $19.00. Its probably safer than the circular saw and since the wheel is smaller its more precise and easier to work it in places. Wear eye protection when you use the power tools.
