Hi all I was asked by a few people how I did the leather so incase anyone is interested here's how I did it.
First I primed it
Then a very watered down coat of yellow ocher (I only used vallejo as I didn't have any yellow ocher in enamel, but enamel should work too)
Once that's dry a very thin coat of humbroll 62
Then a normal coat of humbroll 63 then whilst it's still wet, scrunch up some clingfilm film and dab it on the paint till you get the desired effect.
Then a coat of satin varnish
If I wanted to take it further I could scratch the paint then rub some buff coloured pastel into the scratch, brush it off then varnish it again.
I could go on and pluck holes in it put oil stains and all sorts
It's dead easy .
