There are a few tricks on creating faux rust on objects,
but this one is probably the easiest!
To make faux rust Christmas letters:
you need pre painted white wood letters.
Ground cloves and cinnamon.
On a newspaper covered table, use a paint brush to spread the glue on to each letter one by one.
Sprinkle/ or sieve over the cinnamon.
Add more glue is needed to throw on pinches of cloves..
The cloves is darker than the cinnamon so it gives a nice rust worn patina.
I created a rusty 'HOHO'
How cool is that?
The bonus is all that cinnamon and cloves is
making my sitting room smell 'Oh so much like Christmas'!
