To make the feeling curious, I have a little template I use to transfer the 'keyhole' onto the feeling. I trace the template with a blunt pen. Then I cut out the sides and the hole. When the clay is still soft, the sides usually get a bit wonky so I use a thin piece of wood to make it even again. To finish it off, I use my paintbrush with a little bit of water. That last bit is the most intricate part of it all and practises my patience...
