After experimenting with backgrounds, I have decided on the current one with the cute fresh green feel and pink flowers. It was designed by Blogaholic Designs (click on link) who have some lovely free templates, backgrounds and buttons on their website. You can see some of the buttons in the sidebar (e.g Welcome to my Blog, Comments Brighten My Day) and I think they really personalise your blog- I love them!
I also had a go at designing my own 'Follow Me' button using Picnik (free online photo editing software) which was great fun and ensures your button is unique. I reccommend any other bloggers have a go ! :)
