*Mix one cup flour for every cup and a half of water into a pot.
*Boil on a very low heat, stirring constantly. (with a wisk, if possible)
*Continue boiling/stirring as paste becomes thicker.
*After approx. 20-30 mins., paste will become thinner and more transparent.

Whether you're pasting artwork, political posters or fliers for a show, wheat paste is a good medium to glue them up with. Unlike wallpaper paste, wheat flour is cheap and easy to get a hold of. If you're going to be doing a lot of pasting, a bucket with a lid, a handle, and a paint roller work well. Otherwise a plastic container with a lid will hold enough.
Pour dry wheat flour into the container about 1/3 of the way full. Slowly mix it with water, stirring as you do so. You want the wheat paste to be thin enough to paint onto walls but thick enough to stick.
To put something up paint the wall with a thick layer of paste and smooth your poster over it. Make sure you glue the edges down. Don't paste over the poster or you won't be able to see it. Wheat paste is not clear. If you're worried that the poster might get damaged in the weather, or if you want to make it harder to take down, spray [or paint] a clear coating of shellac over it. The wheat paste sticks best to surfaces like cement. If you put the poster up well enough the only way anyone is going to be able to take it down is by buffing it off.
