I have a remote suspicion that some people concentrating on the wicker fences only didn't take a look at the whole thing. I had a good reason to crop the preview pic...
How much do you get in one £12 pack? The GW webstore only says "4 long sections, 5 short sections, and 2 signposts". What's that in inches?
A long section is roughly 18-20cm (7-8"), a short section is 7-9cm (~3") and signposts are obviously small. They're all completely different so the lengths vary. The whole set is about 120cm (47"). That's quite a lot of fence, I'd say. Enough to block all movement in RnF based games.

My lot comes from the fortified manor box. It was maybe 40% off at the local independent retailer so it didn't really break the bank. I paid 40e or so and these fences are only 1/8 of the stuff there. No idea when I find the time and motivation to build the rest. They're nice, detailed pieces but take some cleaning as a large mould line runs through every single bit. That's plastics for you. On the positive side, you can kick those pieces around quite freely and they're unlikely to suffer any major damage.
By the way, all those building sets are actually made of four basic components: watchtower, chapel, stone walls, and fences. My pic only shows the fences. Stone walls are still different. They're used to build a small walled yard. The boxes go approximately like this:
- chapel = chapel
- watchtower = watchtower
- fortified manor = chapel + watchtower + stone walls + fences
- full building set = fortified manor + chapel + watchtower + 2 x fences
...but that's actually 2 x chapel + 2 x watchtower + 1 x stone walls + 3 x fences
I'm not 100% sure about the formulae but the main point is that they're different combinations of a few smaller components. Especially the manor house is essentially just two smaller buildings glued together. You can assemble it in any way you want.
And yes, very much Finnish and living here in the north. Not the best place in the world for alternative gaming but I can try. Nowadays I'm more into painting and building anyway.
