Stitch 65 is the Buttonhole Bar: http://pintangle.com/2013/05/07/take-a-stitch-tuesday-stitch-65-buttonhole-bar/
I got kind-of behind what with eye surgery and all but finaly caught up last night with Stitch #65: the buttonhole bar:
I can see this doing a really really neat layering effect on top of other stitches! And it was fun to do! If I'd had more time, I would have tried it with different threads but getting one row done in perle cotton was good enough to learn the stitch.
