I am considering a solo DIY tarp. It would like it to be as simple and light as possible. Maybe just a 8' x 8' rectangle to use as a flying wedge or A-frame. I do not need mosquito protection where I hike. What Material would be best? Sil nylon? coated Nylon? I forget what the call the stuff they make door and window weather covers out of, but that might be a possibility too.

Tyvek is the most common brand name. There are some other competitors on the market, too.

I think he might be referring to polycryo rather than Tyvek.

Silnylon works well. I made a Ray-Way style tarp from it, and the only disadvantage I've found is that it tends to collect a fine coating of dust, I assume due to static electricity.

A long time ago my then-girlfriend made me a 10'x10' tarp of 1.9oz. PU coated nylon. It worked well, but heavy by today's standards (about 2 lbs.).

3- or 4-mil polyethylene, usually only available in black or clear, but occasionally in light gray, also works. The corners can be secured with sheet bends, but you need Grip Clips or similar for other pullouts:

Note, by the way, that Grip Clips won't work on silnylon since it's so slippery. I've read that you can make it work by putting a thin piece of rubber (cut from a balloon) between the clip and the fabric.

Polycryo is both inexpensive and very light, not to mention it's easy to build with. The only problem is durability. Folks say if it starts a run, it will keep going, though I haven't experienced that yet. If you do use it, make sure you "hem" all the edges with that 1/4" double sided tape and that all the guy lines have elastic segments.

If I had the time to make another tarp, I'd probably try silpoly myself.

I've made several tarps, starting with SilNylon, but switching to SilPoly. There is not much difference working with either, but the SilPoly should be longer lasting and not stretch as much wet. I hem the edges and sew Grosgrain ribbon loops on for tieouts. Where I have seams, I often sew extra tieouts on. Depending on the use, I often sew a strip of Grosgrain ribbon into the hems on the edge. It adds strength to the edges and allows me to pull the tarp more taut.There should be plenty of plans online. You don't need to use one of these plans, but they can give you some insight into why things are made the way that they are. Long hems and seams in lightweight material are not easy for those of us with limited sewing experience. That's the main reason that I use Grosgrain ribbon in mine, it adds bulk and helps to keep things straight.
