OK, you don't have to imagine. I took pictures. Not many, because I was having too much fun running around watching the guy at the ear wrap booth attach elf ears to young and old and trying on masks and being on panels and listening to Brian and Wendy Froud talk about art and magic and the fairy world. But on the theory that a picture is worth a thousand words, and I'm short of time just now, here (if this attachment thing works) are my three favorites.

As you can see, everyone had a wonderful time. There was a Good Fairy Ball. There was a (much bigger) Bad Fairy Ball (and what does that say about the relative sartorial possibilities of goodness and badness, eh?). I wore my crafty friend's hand-dyed silk Luna Moth wings to both of them, over green velvet for Good and with a black bustier and a Lady Hamilton-like wig for Bad. There were fairy fashion shows, presenting a new line of fairy god-mother wear designed by Wendy Froud and made by Gypsy Moon. There was Ellen's Thomas the Rhymer show, with fiddler Joe Kessler (which I couldn't go to because I was on a panel at the time). There were book signings and friendly dinners and many LJ friends met and greeted. There was even some writing, in a little tea room serving matcha lattes and Japanese green-tea sponge cake.
I'm already looking forward to next year. And soon now, very soon, I'll be sending pictures to the people I've promised them to.
