I've been working on organizing stuff in my office and decided to use luggage tags to label everything. By creating a generic tag, I can write on the outside w/ a dry-erase marker or wet-erase marker, making labeling easy. You can use the same concept for creating a reusable gift tag, or labeling any container that you use. I wrote more about it on my blog.
