As I have so many bases to do, I have been trying out different techniques to base them quickly. I think the one I will go for Is my tried and tested 'paint on muddy footprints method'. This looks effective and Is the quickest to do. I have the added bonus of having a range of Silflor products to help now which should enhance the bases further.
I mixed up a muddy glop with added gloss varnish for the mud on the bases, I'm not quite sure about It really, I will have to sleep on It and decide tomorrow If to keep It.
