Hola, iam Lorraine Conley, Take it easy.
What Can I Put On Paper To Make It Hard? [Solved]
If you want to make your paper stiff but still be able to work with it then I would recommend Mod Podge Hard Coat. You can apply it to your paper in thin layers (let each layer dry for 20 to 30 minutes). Just add layer after layer until it is stiff enough for your project.
