Help!

So I am trying to figure out how to make it so my whole background matches! I want to get rid of the dot background that is around my posts. Can anyone help me out so that the cute backgrounds can be seen instead of this annoying dots around my posts? I hope I am making sense and someone can help me out here. I look at everyone's blogs and they don't have the different background under their posts and I want mine to look like that. I am getting frustrated because it isn't working and I don't know what to do!! Please someone HELP!!!

GOING PRIVATE!!!??

So the other day I was ready through the November Ensign and I read an article on blogging and it made me a little nervous. I don't know who is reading my blog so I am thinking about going private. It makes me nervous to think who could get on and read about out lives. Leave me a comment if you want to get invited because I am ready to go private so people I don't know can't look at my sweet little family. I will probably go private in the next couple of weeks so let me know your email addresses so I can invite my family and friends to view my blog not weirdos!!!
Maybe I am overreacting but who knows what can happen and I want to protect my family!!!
By the way the article was only a page long but it gave great advice on blogging. It didn't say it was bad but that you should just be careful what you write about and to never give addresses of where you live so I just want to go private after reading that!
