Oh, you know I will definitely post photos when it's done, Kyle!

Yep, around 4 yards is what I'm going to shoot for. I may adjust the length a little for my height and build so it's a good fit both when folded/draped and when wrapped like a cloak. I will probably do a mock-up using my wife's good bedsheets pinned together to find the right length. I'll use the plaid flannel ones, though, so it doesn't look too much like a toga.

I've been reading up on old threads for the fringing/purling process. Good Lord, that's going to be more work than I thought it would. Based on AKScott's excellent thread, I'm guessing it will probably take me weeks to get the whole purling process done. But it'll be worth it in the end, I'm sure.
