I also will be offering premade blog sets soon so be on the watch for those. Here is a FREEBIE blog background for you though! It's in a 3 column format but will look just as fabulous on a 2 column blog. You can visit my sample blog for a short time to see what this background looks like in action at http://polkadotscrapssampleblog.blogspot.com/. (Please do not redistribute this background in any way. You must display the credits provided if you use this blog background on your own blog.)
I had originally forgot to add the code and instructions but it's in there now!
