Do not Adjust Your Computer Screen

Hey everyone! I'm just changing some things around on my blog. I wanna new layout and design I think. I'm not sure what I'm looking for but I'll know when I find it. For all my fellow bloggers, did you get someone to design your blog? If so who did you use? If not, what do you do to to change your layout and design. I'd like my blog to be more professional looking. I hope everyone has a very Merry Christmas!
Love ya'll!
