They could have a flask. For holy water, of course.
This one's holy water. This one's whiskey.
And they definitely could market a John's Journal.
Years (and years) back, when my office discovered Daytimer planners, I didn't like the format. I went to our local independent stationer's and picked out a three-ring binder, chose the type of calendar pages that work for me, the monthly tabs and phone directory pages. There's a zip bag for post-its, pencils, pens, stamps, rubber bands, paper clips, and there are clear pocket pages for photos, plastic pages divided into slots for business cards. There are a couple of heavy plastic dividers with pen loops where I attached binder clips, for holding loose stuff. I made section tabs out of card stock, and kept a file of photographic and drawn and painted artwork clipped from catalogs, along with motivational and inspirational sayings to glue onto the heavy colored stock. I had a section of thick, textured notepaper cut to size and punched, and carried about a half-inch thickness of pages to use as my journal, removing and replacing pages as I wrote on them, binding the loose pages, when I'd accumulated enough, with binders I'd covered with giftwrap or fabric. There was a section of blank drawing paper and another of lined looseleaf paper for notetaking. And sprinkled all through the binder, through all sections, were pages of colored stock with pictures, drawings, photographs glued on, doodled on, scribbled on in colored pencil and ink.
I still have that binder, and use it today. Its use has evolved. But it has some similarities to John's journal. I feel a little thrill of kinship when I see the journal onscreen.
