I played around and found that it is hard to make it look neat and tidy on a curve, it resembles a crunched up barbed wire.
I also found that I have a tendency towards making the two arms V-shaped, but the upright ones look OK, too.
May I suggest that you:
1) go to Pintangle to learn this stitch
2) post a photo of the result on your own blog
3) leave a link to your blog post on the Comments form at Pintangle
4) let others see your work and look at what they have made
5) have fun!
