Sure, you could also do it that way. I just based my suggestion off the following passage from the original comment above:
> For wilderness canoeists
In that case I would still suggest going with the laminated maps over the ziploc bag since once moisture gets into the bag containing paper maps you've already started them on the road to colors smearing, mold, etc.
Zip-lock bags (even the heavy-duty zip-lock map bags) don't cut it. If you get even a trace of moisture or condensation in the bag, it evaporates and re-condenses causing a disproportionate amounts of smearing.
The problem I foresee with self-laminated sheets is that the original maps are about 24"x29", and when you cut them into printable 8 1/2" x 11" sheets you need to account for non-printing margins and (sensibly) provide some overlap between adjacent pages. So somewhere between 9 and 16 pages per top map (depending on whether you're blessed with borderless printing). It's quite an ordeal to print them yourself. Even more so if you have to laminate each sheet. On a typical trip, you'll use 2 or 3 maps (48 pages). On long trips much more. Workable, but a real hassle. It's certainly going to be a pile, compared to
You could be selective about which pages you print, I suppose, but I find it comforting to have enough surplus map to know what your escape points would be, should you be faced with an emergency.
God bless Her Majesty's network of Certified Map Printers.
Couldn't you laminate the maps yourself, when you're already going through the trouble to print your own?
