Suggestions for making "4-up" fliers in MS Word.

Start with an empty document. In Page Setup, set margins on all four sides to 0.5". "Select All" and define TWO EQUAL-width columns with a 1.0" gutter (twice the margin size).

I don't set up any formal formatting for the vertical division -- I just adjust the height of repeated text content and images to flow to top of the right column. [There's probably a better way to do that in the newest versions of MS Word, but this works].
