Paper:

Recycled paper is available everywhere now at competitive prices. Even better, try a tree-free paper stock and see for yourself what the fuss is all about! Want to drool like me when you touch paper? Try Sakura by New Leaf in your next project. Here's are some vendors for 'ya:

Online Stock Photography:

There are two kinds of online photography available: royalty-free and rights-managed. When you purchase a royalty-free image, you can use it anytime you want. Rights-managed photos are one-time use, and varies in price (usually more expensive). These are the ones I used the most, but just type in your browser "stock photography" and other websites will pop up.
