Definately put it on a ship forum. I would guess that, if the colour on the paper side shows through well enough, you would be required to cut them out, fold them around the pole or wire, get them in register and then rub them together, as pressing the two waxy sides together should make them stick. Of course, they may be meant to be transfered onto a small piece of cloth, one on each side to make the flag. I'm not sure.
You'd best find someone who's worked with them before.
