Michelle has combined 50 different links to posts about blogging. There is everything from blog design to promoting your blog.
To make my own social media icons I used Kira's post from A New Leaf. She also has a whole section called Primp My Blog with lots of information on blog design.
I still have a few things on my blog that I need to update and change, but like I said before it will probably happen slowly. So please be patient with me as I educate myself in the blog design world.
