It looks like a crochet chain to me. If you look at the second picture on this listing you can see the back "bump" you get when you are crocheting a chain and the original picture you listed shows the "V" formed on the right side of a crochet chain. http://www.etsy.com/listing/96485281...ref=v1_other_2
So it looks to me like it a crocheted from some VERY bulky yarn (likely a couple strands)..with an eye lash yarn too.
Looks really easy if you know how to crochet!
