I've redone my blog layout about 50 times now and in the process created a ton of blog backgrounds (stripes and chevron). None of them fit into my final layout choice, but I think it would be sad for them to go to waste.
These are completely free. Use them for whatever you'd like.
It's not necessary, but I'd love if you'd link back to my blog. The only Do Not, is please Do Not claim them as your own.
Just click on the Image to see it full size and the right click "Save As"
