What kind of bun do you want? There are several different ones. Do you want to have a bun where your hair is in a bun, but you still have some hair out of the bun? Or what kind of bun is it that you're looking for? If you clarify your question a little more, I'm sure I can help you! ..(watch..you're probably not even talking about hair and this post is going to make me look like a complete idiot! LOL)
