I definitely need a swayback adjustment, and possibly a smaller bodice size. I'll see how it fits once it comes out of the dryer. I attached the neckline binding, but just turned the sleeve hems over and stitched them down.
If you're making this out of a twin flat sheet, save your sanity and buy the fitted sheet or pillowcases as well. This might be the one instance where it's less fiddly than fussy cutting the top sheet.
