Paper comes in a variety of thicknesses and designs, but the paper you want to use for your project may not be thick enough for it. Some craft projects involving paper need extra support, especially if you are building boxes, walls or containers for your project with the paper. Luckily you can harden even the thinnest paper types, such as tissue or notebook paper to increase stability and allow you to cut, shape and build with the paper of your choice.

  1. 1

    Lay a sheet of waxed paper over a table or workspace to protect it from glue.

  2. 2

    Lay your sheet of paper that you want to harden over the centre of the waxed paper.

  3. 3

    Pour 29 ml (1/8 cup) of white glue into a disposable bowl or cup.

  4. 4

    Brush the glue over the paper in a light layer with the foam brush. Do not let it pool up; just brush an even and thin layer over the entire paper. Allow it to dry for 20 minutes.

  5. 5

    Flip the paper over and brush a light layer over the other side. Allow it to dry for 20 minutes. Feel the paper to test its hardness and apply more layers to each side until it is as hard as you need it to be.
