You'll find the screen cloth and the holder at any hardware store. Buy one course and one fine.

Once you have the patch sanded, you'll probably need to paint the entire wall; otherwise the smoothly sanded patch will show up like a neon sign next to the roller-pebbled painted surface. I'd suggest using a small 3" roller and interior latex primer to seal and prep the patch for standard latex paint. Then paint the entire wall with a standard 9" roller to even out the surface texture.

If you have damaged dry wall and the holes not too large, it's very easy to fix for yourself. What you want to do is get some fiberglass mesh tape, which is specifically made for wall board joints, and just cut off a section of it, maybe a couple inches, three inches longer than the span of the hole there. If you get the kind of fiberglass tape that self-adheres, it's even better and you don't' have to put a coat of joint compound down first, which you would have to do if you got the kind that did not have an adhesive back to it. And I'll show you what I'm talking about in a moment.

And I would say square it up and make it look as good as you can like that. And the next thing you want to do is get some joint compound which some people call mud. And take a little bit of it on a spatula or a putty knife and just skim a smooth coat over that. Now, it's going to bubble up on like this and look funny on the first coat but you want to let it dry and then once you do let it dry, you can sand that down a little bit. And what you'll is come back and add at least one more coat a little further out- again, this is after it's already dried- you're going to skim some on a little bit wider, sort of feathering out the edges which will hide the small bump being made by the repair here. And then once again, sand it, prime it, and paint it.
