In my tried and true tradition of making things much harder than they need to be, I decided that I would try making some of my own backgrounds using Photoshop. After all, I have a book I bought years ago that I thought I really ought to use. :) It's called Digital Designs for Scrapbooking by Renee Pearson.
After a whole day of dinking around, I finally got realistic and found some editable backgrounds to go along with the ones that I had made. After a few color changes to make some variety, I had enough to get started adding photos. I digitally cross-processed most of the photos to make them more interesting looking (well, at least I hope they're more interesting).
I really like the way they turned out. These are a few of my favorites.
I'm definitely looking forward to playing around some more with making background pages and other things like tags and stuff that I can use for scrapbooking or mixed media art projects.
