It is free for other crocheters to advertise here. I might consider taking payment for advertising here when I get famous. For now there are only a handful of people reading this blog. So you would be silly to pay me for this. Haha!
Until then, I say share the love :)
Send me a 180x180 picture and link and if I think your product/blog/site etc has something to do with optimistic by nature you're in. :)
