I don’t know if you can call what I do journaling, but I always have a notebook at hand. And if you are going to carry something around with you it should reflex your personality. I like composition books, they are sturdy and easy to alter. Here is a cute cover from Wild Olive that will fit a composition book.This one from Creme de la Craft could easily fit in a purse or pocket and made from recycled cereal boxes. Win win.Sometimes we journal art, not words. Here is one from Creative With Kids you can do with the kids (or for yourself) by altering a board book. They are so sturdy, made to take a beating and easy to find a thrift stores, so why not give it a go.
