Shade arbor
I still owe you a post about my modified shade screen approach, but to me, this project is more exciting. Partly because it's what I've been working on most recently, but partly because I've wanted to do this for a very long time.
A shade arbor might even have been one of the ideas that kick-started me down this path I'm on.

Somewhere along the way, I got the idea to build a shade structure over that concrete slab. Then I got the idea to grow some pretty climbing vines over it. Wisteria sounded perfect. At least until I read up on it and found that it's very "vigorous", and needs a very sturdy support. Plus it takes ages to flower in many cases.

So I thought why not a grapevine on our patio? Beautiful shade plus tasty fruit!
Unfortunately, I never got around to it. I'm not especially handy, and I wasn't confident I could do it. Eventually we moved. And while our new house doesn't have a concrete patio, it does have a number of west-facing windows in the back yard. And I'm even more committed to planting an edible landscape, not to mention cutting electricity usage.
So back in April of 2007, I bought some materials, dug some post holes, stuck some posts in the ground and poured some concrete around them. Then life intervened. It was always second priority. Or third or fourth.
Now, with the tractor dead (again), and the garden in shambles, I'm letting the jungle grow for now. The cow is down to one milking a day, the car repairs and bank fraud and sick daughter are mostly behind us. With unseasonably mild weather hanging about, I decided it was time.
I've only completed half of it, but the second half should be slightly easier, now that I've worked out the kinks.

One thing you can't see is that a number of the posts have twisted over time. I don't recommend taking a year and a half to complete such a project. Another thing you can't see is all the glaring imperfections. "Due to the handcrafted nature of this project..." Like I said, I'm really not very handy.
The decision to make it narrow was not arbitrary. For one thing, it had to fit between the house and the gate in our fence. Well, it could have stretched far enough to reach beyond the gate, but that would have made it monstrous. For another, I wanted summer shade but winter sun. Too wide and it would have been casting some shade all winter too. We want all the winter sunshine we can get! And given the narrow space, I decided to use cattle panels as the top of the arbor, instead of the traditional wood lattice, or the taut wires often used with grapevines. Happy grapevines will live for decades, and I didn't want to worry about someday replacing rotting strips of wood or tightening wire supports. The reason it's so long is so that it will eventually shade two windows and a sliding glass door. And the reason it's not attached to the house is so that we don't need a building permit, so that we don't create a highway for ants and other bugs to get in, and so that we don't end up with grapevines climbing onto the roof. (We may get those last two anyway, but it should be easier to prune away from the house than if it were attached.)

Here you can see the shadow being cast by that canvas tarp:

If you want to see how much sun or shade you'll get from an arbor, awning, or overhang, this tool is invaluable. You use sliders to set the dimensions of your window, the dimensions of your shade structure, and your latitude and longitude (easily obtained via Google), you see what kind of shadow will be cast at different times of day and year.
In any case, it sure is nice to have a structure out there, instead of just some random posts sticking out of the ground.
