This past week I've undertaken the self inflicted task of making my own hex tarp (yes, with cat-cuts.) So I went to Dutch's site as well as RSBTR and got a few things.

It can out about 11' x 10' with 5" cat cuts. Some silnylon, thread, and some shoddy sewing gave me a decent looking end product (with a neato color combination of I do say so myself.)

My Zing-it hasn't come yet so I can't set it up. That's killing me.

BUT you can take a look here:

And see my process on this project!
