That is a question.
I think my blog is special because I like to share. I don't just share things that I make, I share other's products, items, feature other Artists (from Etsy) or those that I know in real life vs internet "friends". I try to keep topics fresh as well as have days devoted to specific topics. There are photos, tutorial videos, links, and I'd like to think not only is it informative but entertaining.
I try not to blog too much about personal things, but I list items, new projects that I am working on, new materials that may relate to other craft-people.
I think every one's blog is special because it reflects them, their thoughts and sometimes their process, making it unique to them.
