Ok, now I’ve got a garage full of RTV rubber and resin I’m looking to create some more masters so I can create some FOW terrain. Here’s a handy tutorial from ‘Digital Dioramas’ regarding making those good old sandbags.
The rest of the Digital Dioramas site is definitely worth checking out as well. There’s some stellar work up there from serious historical modellers.
WW2 Model Maker is another excellent historical modelling site btw.
