I can't do this....

I really want to have an awesome active blog with giveaways and great info, but, I can't get anyone to follow me.  I currently have 12 followers that I am grateful for but would like to have at least 25 before I do a giveaway.  I am not a computer person so I can't fancy my blog up like the ones I follow.  Not sure what to do.  Any tips or tricks to getting followers?????  Please any info/comments are welcome!
