Thought I'd quickly post this picture. I bought these haystacks at Broadside and quickly painted them up a couple of days ago. The models are resin and although they are supposedly 15mm scale they could easily be used for 28mm wargaming as well. Made by Mainly Military resin Scenics and sold by the Plastic Soldier Company.
The paint job couldn't have been simpler. I cleaned both models with acetone (acetone based nail varnish remover will do) then undercoated them with GW white primer. Each model was then just washed with Vallejo dark Flesh in wash and then drybrushed with bright yellow for highlight. Then I painted the ground dark brown with some simple highlighting. I decided not to add static grass as I thought it looked better like this.
I finished off with the usual GW Purity Seal satin varnish and then two coats of Testors Dullcoat to give them a Matt finish.
