I've been making my own waterproof log books for a year now. Two hundred sheets of Rite-in-the-Rain paper ran me $30. So my average 12 page 3"x5.5" log book costs 60 cents and I can publish 50 of them. Of course, all my covers are custom, but here's a generic template for the masses (i.e. all four of you who read this blog). Cover. Lines. Print, cut, fold, staple, and then reinforce the spines like this: Fold a strip of 1/2"waterproof first-aid tape over the top. If the tape's adhesive is lame on the specialty paper add some contact adhesive to beef it up. Practice on cheap paper first and stick with laser printers. Bonus: You can tell your friends you've gone into publishing.
