I tracked it back through Pinterest, then to another facebook site, but I'm so happy I found the original designer this morning. Thank you so much for the pattern Yella. Check out her blog. Here's the link.

I made a few on the weekend, so that I had a couple of pics for the page, I didn't have a plain white lampshade, so this had to do. I changed the teeth a little from the pattern but that's just me fiddling....I like the original teeth just as much.
The pattern is written in Swedish terms, there's a great photo tute, but if this helps -
an air chain, is our chain, a chain is our dc.. I think? (sc for Americans).
I used 8ply/dk and a 3.50 mm hook, and they turned out 10cm high. Very cute pattern!!
When I finish what I'm doing atm, I plan on making another project with the skulls, I'll come back and post a pic when it's done. I'm a bit excited, to see what it will look like. No not a tea cosy that's already been done :-)).
Go and thank Yella for the pattern, it's a nice thing to do :-P
Thanks for visiting,
