A chainmail hair tie:
Johanna pointed out that I shouldn't advertise this here, so I'm reducing it down to the announcement that I will be selling it and nothing more about it. You can bother me personally if you want to know more about it.
I think that this pushes things back over to the "announcing an event" rather than advertising, but I'm happy if anyone else has an opinion. If anyone else thinks I'm abusing lj, I'll delete this post.
