I can always do each side of the pillow different - that's an option too. I think black and purple would depend on how dark the purple was... but I could always pop into a yarn store and see if I can find a good purple that's not so dark that it makes the black hard to see.

Supplies for the pillow costs about $25, so friendly rate would be $25+whatever extra you want to give me. If I was selling them to strangers, I'd probably charge $50. Mind you, that's all Canadian... so, with the exchange rate as it is, that's actually less than it seems.

Is there a particular group on FB that's good? I wouldn't even know where to look on tumblr. I might have to wait until after the season is over - my being spoiler-phobic means that I can't follow that many SPN blogs on tumblr.
