Renedra have come up with some very effective plastic scenery kits in recent years and I've previously made up one of their wooden pontoon bridges and some of their barrels. This time I had 2 packs of their fencing, about 2 feet in all.
I based everything on strips of plasticard, mostly 2 fence pieces to a strip (making about 6"), with a few singles. I cut across the corners of the bases so that the fence ends could butt up as closely as possible. The usual basing materials (mostly sand and glue) were added to the bases (some time ago I have to admit) and everything got a black spray undercoat (much more recently!). Painting was super-quick; brown, grey and sand drybrush layers on the wood, and my standard green and brown bases. About an hour in all yesterday evening.
Nice and simple, but very effective I think - and a real bargain, especially when you're bought them as a present! :)
