Don't go clothes shopping, Am an anorexic shoppper, truly. Actually I was psyching myself up to go on a big shop to replace frayed old clothes, but then fell PG, so probably have to wait a year now. At least I can be reassured I wouldn't have found much I liked, anyway! LOL.
Good luck with your slings. I would plan for it to be a labour of love and pride rather than anything you'll make much money out of.
