While the Scarves of '03 are great, my favorite December MC has to be the Timepiece from December 2007.
Not only his the hat deliciously steampunky (perfect balance of steam and punk) but the boots have been some of the most useful boots I have. I love the color of brown on them and they're part of my favorite outfit:
I joined gaia in 2006 so I was in awe of the MC's that came before me, but looking back over them I think I was actually most impressed with the December MC's of 2007.
Specifically I really love the Snow Witch. It can add such lovely texture and can aid itself to a variety of themes; from the dainty gloves to the menacing hooded cape. I think it was also one of the first MC's that started having really lovely pixelation.
The apparel was great and I love the coat.The background was beyond awesome and had me wishing I'd purchased another. The blade was wonderful and gaia could always use more masks like it features. 3nodding
I joined during 2007 and most of my earliest dream avatars include WINTER ROSE. Since then, until now, I always liked it. It's feminine, white, clean and beautiful. Those old 'dream avis' I made are still compiled in my journal. The item just reminds me of my newbie-ness and good old gaia days xD.heart
