HARDENING THE SHEETS (1)
Allow the first sheet to dry and then cover the other two sheets with Alkyl. Paint one coat of Alkyl and make sure that you paint it thickly on the front part. Let it dry.
Paint another coat and let it dry. This way we are making the paper harder so that we can then shape it.
Do the same with the first sheet, give it a thick layer of Alkyl and then let it dry. Now we have hardened the three sheets they are ready to use on the front part.
