I first visited Paper Source when I was designing programs for my wedding ceremony. I was blown away by their selection of papers. Truly amazing. The prices are expensive, but the papers they sell are beautiful and unique. There are books and books of other people's projects to inspire you, and if you are not artistic, they can also set you up with a professional to make your one of a kind invitation, program, etc. They also sell wrapping papers, stamps, and more.
