I am proud to announce that I posted my first sized "for sale" pattern today on Etsy and Ravelry! It's a poncho done in Tunisian in the round. Awesomely (like that word? You have my permission to use it any time!), the fabric is reversible. There are several video tutorials linked in the pattern, all about Tunisian in the round, and certain Tunisian stitches used in the pattern.
(ETA - new/better pics!)
