Thanks Saya! Yep, the pattern sure is available online.
It's a free one on Knitty.
I found the fishnet pattern extremely easy, the worst part was redesigning the pattern to fit my smaller legs/feet and make up for the fact that my yarn was a different weight with zero elastic. (That's why it's chunkier than the Knitty pic.)
Next time I knit these I want to try using Patons stretch sock yarn, as Esprit and Cascade Fixation both have high shipping costs for Oz.
