I found what I thought was an extremely good tutorial for making a pamphlet using LibreOffice Writer. Some of the problems that I thought were problems with making pamphlets in Writer are not actually problems and this tutorial addresses those things and much more. The most interesting part to me was using frames instead of columns. This allows you to have different backgrounds for different pages of the pamphlet if you so desire. Anyway, here is a link:
