Of witches and a particular witch's symbol

I've missed you and the bloggingz so much! I don't know if I can post often till after this quarter, when I graduate (finally!), but I wanted to pop in for a Halloween greeting.

A couple days ago I figured out what I should do for this Halloween, costume-wise I mean. I haven't gotten to craft much lately, so this also gave me a chance to crochet.

Anyone recognize this? Sorry for the quality!

If not, follow this page (spoilers for Madoka).

Yep, it's the grief seed of my favorite Madoka witch, who's outfit (well, an anthropomorphic version of it) I can luckily pull out of my all-black closet. >:D
