Brian’s backdrop ‘how to’

“Hi Al

Here is how a do my 3D backdrop.

I use 3mm (1/8”) Masonite (hardboard), makes no difference which side I use for my backdrop.

I cut it to the shape of the mountains that I want as well as the length.

Start with a coat of earth colour latex (PVA) paint over the whole area.

Mark out with a pencil where you want the closer hills and the hills further away.

Paint on white glue in a thick consistency starting at the bottom.

I use 4 colours of the ground foam from darkest to lightest.

Start at the bottom (closest) with the darkest green and work your way up using a lighter colour as you go.

Remember that the closest mountains are always darker that the furthest ones.

When all is dry, I mark out the different hills just to enhance the look of distance between the hills.

The photos show how it was done on 3mm thick Masonite for a section of my backdrop behind and under a bridge section.


A big thanks to Brian! (His original post is here).

Ebay cheat sheet is here folks.
