Building vignette "Sum of all fears" with Dremel tools. I used mostly my favorite tool: model 7700, very handy little helper. To drill all necessary holes to put fence on wooden base I've used Dremel 7700. For sanding pillars I've used Dremel 8200 with special sand ending.
Earth effect by Gale Force medium basing grit. As a base coat I've used Vallejo Spray- black primer.
Barbed wire fence is great Plusmodel product. Figure from Masterbox set number 3567.
