I took some better pictures of my woven scarf today. I also washed it to full it, rolled it in a towel and laid it out on the deck to dry under the canopy. It softened up quite a bit, too. My wonky edge is certainly visible but I'm sure my edges will get better with practice.
I learned a lot from "Hands On Rigid Heddle Weaving" - a book Stephanie loaned me. And "Weaving Made Easy" from the library was a great reference, too.
I think I'd like to weave another scarf using sock yarn, doubling for the warp and the weft for a faux basketweave look.
