Using distress paints and alcohol inks
With a paint brush stipple the colours and cinnamon together
and finish off by dipping the cog in the left over cinnamon.
Leave to dry and if you're anything like me you will help it along with your heat gun - oh boy the workroom did smell nice.
When cool I rubbed off some of the excess powder and I think I will buy a spray matte varnish to seal it.
Repeat the process again to get more texture layered again heat drying and getting some of those texture bubbles.
Paint the colours on thickly and then dip the shape into ordinary fine sand and heat dry.
