Some time in seminary (now many years ago) a seasoned minister advised me to "start getting my 'book' together" -- by which he meant services for weddings and funerals. And uniformly in a half-letter-sized (5.5 by 8.5 inches) three ring binder. It was covered in black vinyl, which was utilitarian. if not interesting to look at.
I had used identical binders as a kid -- we're talking the early 80s now -- for my stamp collecting, but at least they came in different colors! Around 2000, these black ones were all that I could find, and even these became scarce -- they do wear out -- so I bought a couple in case they vanished completely. But then they returned, even in colors, but in an over-designed way that made them better for a commercial office but ugly for worship.
Well, lo-and-behold if the new Martha Stewart line of home office binders doesn't fit the bill, including this very nice one in pebbled brown paper. At Staples, $7. Made by Avery, who also make the commercial ones. Indeed, the locking-rings mechanism is identical, so all the now-available tabs, paper and binder whatsits will also fit.
