My Backgrounds work with most Blogger templates, but they ALL work well with the Minima Template.
Step #1: Find your cute background Here! Select ALL of the text in the box below the background you want.
Step #2: Go to you Layout tab and Page Elements screen (below) and click on Add a Gadget (circled).
Step #4: Paste the code that you copied from Step #1 in the content box, like you see below (you do not need a title). Then Click Save.
And Voila!! You have a Way Cute Background!
