As a rule of thumb, the paper scraps should be about 1 inch (2. 5 cm) long and wide. Rip the paper by hand for the best results. Cutting the paper with scissors is doable but won’t work as well. The water will soak better into the paper if it has rough edges.

If you plan on using a blender, you don’t have to let the paper soak all night. It will, however, give the pulp a softer consistency.

If you do not blend the paper after breaking it down with your hands, it may have a rougher texture that is harder to write on.

Depending on how much pulp you’re making, you may want to blend it in batches. If you choose this option, mix all of the batches back together in a bowl when you’re finished blending for a uniform consistency.

If the pulp is watery and lacks a thicker, soup-like consistency, it is most likely too thin.

You can store paper pulp for up to a week at a time.

If the pulp is too thick, add more water to thin out its consistency.

If you have an old, torn window screen, cut it to the size of your pan and use it to make paper pulp. You can also buy non-rusting screens from hardware or home improvement stores if you don’t have old window screens.
