This stitch, the Reversed Buttonhole Bar, done four ways...

It wasn't difficult (other than my usual inability to stitch a good circle, that is) once I got the tension down. I like the look, especially in the circles - it would make great flowers!

This completes another "page" in my TAST sampler, the fifth for 2013:

This page includes stitches 82 through 94: Spanish Feather, Siennese, Spiked KNotted Cable Chain, Raised Cup, Turkman, two approaches to Buttonhole Picot, Twisted Satin, Twisted Satin with bead, Straight Feather and two variations, and revised Buttonhole Bar.
