At this point, we’ll have to add a binder to hold the paper particles together after the mixture dries. If you have some dry wallpaper paste, dissolve about a tablespoon of it in a little water. Then pour it in the bowl, and stir it in well. If you don’t have any wallpaper paste, try either dry or liquid starch. Ordi nary flour might also work.

To remove excess water, we’ll need a screen. For this purpose you can use part of a removable window screen. You won’t hurt it; it’s just going to serve as a strainer.

Have someone hold the screen over a cake pan while you pour the mixture onto it. Spread the mixture out like a very thin pancake. Then lay a sheet of waxpaper over the mixture, and roll a glass or jar over it to squeeze out the water. Remove the waxpaper carefully, and allow the mixture to dry.

When the mixture dries completely, the paper can be peeled off the screen. It will probably look and feel more like gray cardboard. Nevertheless, it will be recycled paper. And you will have done it . . .basically the way it’s done in industry.

Oh, by the way, if you borrowed the screen from a window, better wash it off and put it back (or else).
