I did an under-painting first, and then used resin sand for the distressed wall (I added colour first), which I applied with a palette knife.
The surround I painted a dark blue and then used a stencil with two shades of gold.
The inner surround is paste through another stencil.
The door itself I have "studded" using a pearl pen, which creates 3D dots. I found 2 rings in my box of delights, no idea where they came from, but perfect for handles.
There is a saying that I came across many years ago, and which has stayed with me - no idea who said it -
There are things known and things unknown,
and in between are the doors.
Only two more projects on my course, and I've managed to keep up apart from the very first project, which is still waiting to be finished!
