The Dux Brittaniarum rules call for eight inches of fences for a village. I think the best way is to make a series of short pieces, say three to four inches each, and make three or four pieces.
The bases here are 2mm MDF, which is not always the easiest stuff to get hold of, but Jackson's Art usually carries it in various sizes in their mount boards section. A narrow strip of wood, chamfered with a plane, gets glued down to the centre. This gives something for the fence posts to sit in while not making the fence so wide that any mini's are miles back from it. Plus it make the base of the hedge wide enough to retain a decent level of stability on the table.
Bases, common to all
The first bit of fence is made the same way as the pig sty fence here, with cocktail stick posts and MIG wire woven through. I made two four inch sections. This is the sort of fencing that might be put in quickly as a temporary fix, so short sections give some versatility. This is quick and easy but only moderately robust - the cocktail sticks don't give a lot of strength. If this bothers you use the variations below.
Woven timber fence - entry level!
The second bit is a post and rail fence made by gluing sections of bamboo skewer into holes in the base. The rails are made from bamboo skewers split lengthways. The post structure is stronger, but the rails can become detached (just like the real thing actually). A single eight inch section of this represents the baseline sort of fencing you might find.
Post and rail - a little more up market!
The third piece uses bamboo skewer for posts, with some 2mm balsa superglued horizontally between them. Two pieces, one about 5mm above the ground level, one 5mm below the top. Then loads and loads of 1-2mm wide balsa strips glued vertically between them. This looks very smart and might well be the early Medieval equivalent of remote-control gates, but it does take longer (much longer) to construct. Since this is a bit posh and pricey, there's only a six inch length (perhaps to go near the church?).
Picket fence - very particular!
I had already kicked this post into life when Gareson put this post on his Iron Kingdoms at War blog. If you don't like mine, you'll love his. If you don't like either, well...
Here they are, all finished. I added scrub and static grass around the woven fences and the post and rail, but not the picket fence. Well, anyone posh enough to have that is going to do his weeding, isn't he? The armoured sub-Roman warrior (finally!) for scale is from West Wind, with a home-made chi-rho shield decal.
