I did not even add that many! I didn't want to spend too long making sandbags out of Milliput once again, so I added a few here and there just to add another feature to terrain. I also decided not to re-paint the other sandbags. What I did do was add a wash of Devlan Mud thinned with Klear and water.
This mixture added a level of griminess which I am happy with and what was lacking from the original sandbag emplacements. I'm not sure if it is evident in the photos.
That should be the last on sandbags. Probably like me you are bored to tears of 'em? More to follow soon.
