3D Christmas Tree Earrings – barely in time for Christmas…

Actually, it's not quite ready yet. It's freeform and unconventional, so I've been uncertain how to write it up. But a few people have said that they're waiting for the pattern, so I will just put this out as is. I'd welcome any feedback – then I can continue to improve my description of this pattern. So, here it is! :-)
[Update March 2017: I have now improved the pattern and changed the links to go to the updated version.]
