Anyone who reads my blog on a regular basis will know I keep changing my backgrounds, headers and just about everything else, partly because I get bored far too easily and I can never make up my mind :(
I was having a whizz around the web today and found some Background and Header sites (all free of course) that you may or may not have heard of. A lot of these I have tried myself :) By the way the sweet header used on my home page is from this link http://allemaalkleurtjes.blogspot.co.uk a site that has some beautiful images for your blog :)
First is http://www.backgroundfairy.com
Fabulous site full of shabby and vintage stuff
If you want a truly unique experience I would recommend this http://itkupilli-cutencool.blogspot.co.uk
She has over 200 to choose from and they are all gorgeous, just remember to go to "older posts" when you get to the end of the pages.
More great images to be found here http://www.thecutestblogontheblock.com
A firm favourite of mine is http://shabbyblogs.com, loads of buttons and post dividers to :)
