In doing a test knit of my Mockingjay illusion knitting chart, I experimented with my bind off to match my cast on. My cast on was done in two colors using the Old Norwegian (aka German Twisted) Cast On with purple as the base and green as the working yarn. It's basically Long Tail Cast On with an extra twist of the thumbloop. On the last row before binding off my knitting, I knit across in green (In hindsight, yes, I could have also worked back an extra row on the wrong side in purl. But, this was a test knit, so I wasn't really going for perfection.). Then, following Jeny Staiman's directions for doing her Interlock Bind Off (Knitty link; Ravelry link) for stockinette stitch, I added just one simple element: I twisted each loop to the right (a half turn) before inserting the yarn needle through its front. Here are pictures of each end of my knitting. Hopefully that bottom picture is clear enough to compare.
