Instead of keeping a written journal, I have often made on-the-spot mandalas to preserve memories and experiences. A form of morning meditation capturing a moment in time, done with watercolor pencils and ink, they average about 5" across. Lately I have been digitizing and making giclees of some of the best ones.
Generally these are not for sale, but prints may be available.
