First up, I decided to make some split rail fences. I figured they would be fairly easy and inexpensive to make. I bought a box of flat toothpicks and cut some of them in half. Then I stacked the small pieces up like a split rail fence, gluing down the pieces a row or two at a time onto a large popsicle stick. Once it all dried, I painted the fence brown and painted and flocked the popsicle stick. That's all it took, and I have a quick and cheap split rail fence. Here are some pictures of the results.
And here are some pictures of the fence with a regiment of 10mm GHQ American Civil War Union miniatures.
