Well, I took a look at the scroll in question, and I can see why you're having trouble, heh. I think your best bet would be to look for something other than a scroll with similar edges and such and modify or adapt it. My brain's a little fogged, so I can't figure out exactly what's in my head to give me that idea, but I think it might be a curtain or ottoman or something.

Other than that, if I find some extra time this weekend or next week, I might play around with trying to make one. Haven't tried cloth or parchment, yet. Though your target looks a little more cloth-like to me, personally, if that helps you think of things to go search for.
