To make paper, you will need a frame with an inside dimension slightly larger than the sheets you plan to make. You can use an old picture frame or even a standard window screen frame - anything that will allow you to provide rigidity for the mesh. We found an old piece of polycarbonate plastic and cut a frame out of it as shown on the right. This works very well because it is easy to handle. To create the cutout, we simply drilled four holes in the corners and then cut the opening with a jigsaw. You can also assemble a frame using wood slats along with nails or screws. It doesn't have to be elaborate.
