From "Traditional Lace Knitting" by Furze Hewitt.
This ingenious finish fits most neatly on a multiple of 4 plus 2 stitches. After the set-up row (row 9) repeat rows 10 and 11, finishing on a wrong-side row before the final cast-off.
I suggest that changing the second k2tog in the odd rows to ssk might give a neater effect.
Since posting this I noticed that Jared Flood uses it to finish his well-known version of the Hemlock Ring pattern. It works well with thick yarn.
BTW, I can crochet!
