I use a small business card album to organize current project samples...it's only 8" x4", and isn't very thick, so it slides easily into my bag. It holds almost 40 swatches in clear plastic pockets. I have also discovered baseball card collector's pages. They fit into a 3-ring binder, and usually, I allot a "page" per project. I have a few pages, (same size) that are used to hold photo slides...the pockets are a bit smaller, but are the perfect size for snipets of solid colors!
