I have made art journals for many years and as soon as I completed one (50 pages or so) I would immediately destroy it. I never wanted anyone to find my journals. But about two years ago I began to bring them into my therapy sessions and in sharing them with my therapist I began to appreciate the art I was creating and have saved them ever since. I was so afraid what people would think of me if they found them but really as my therapist has said to me they are really up for "interpreatation" They are not actually written pages. I even published some of them on blurb.com - check it out:
