How can I get some Backlinks to my blog?

I have a blog, and doesn't have enough traffic, I know I have to do a lot of SEO in order to get more traffic, but first I have to get the backlinks to be an authority in my niche so google would show me at least in the first page of the search result page. Do you know any way to get those backlinks. This is my blog: http://the-hidden-spaces.blo.com I will apreciate your help!
