And here's all the subsquent updates merged into one
I'll mostly show updates on individual boards otherwise it may get confusing and i'm into the fine details now. Also because I'm working on 16 boards at once I don't finish the same thing on all boards at once, rather I'll do a few at a time.
Hills and gullly
First hill. I started to run out of caulk so I used some old stuff I had lying around. The colour difference doesnt matter as I will paint them anyway but if it show through I dont mind, because the ground doesnt have to be the same shade everywhere.
On this hill I glued a piece of MDF big enough to fit a 40x40mm base. I have a few features to go on here depending on the period - stone circle with sacrificing druids, windmill or cell phone tower.
To give the gully more depth I added a rocky hill on one side (green foam) and a larger gentle hill on the other. I'm not sure about this terrain mat as it is very ** CENSORED ** and I dont know how much I will use it.
Fields mat
The first picture shows the layout with the ditches carved into it and the road layout. The second picture shows the ditches textured and drybrushed and I glued down a piece of field mat in one of the field sections. I also painted some brown but I dont know what flock I'll use there yet (maybe yellow?)
Small lake tile. With a lake in the middle and I used some older dark AB flock for a field. A piece of the road is under repair. already
First tile flocked! This came out very nice and the contrast between the road and grass looks good. There lots more to do including adding different coloured flock for dried grass, bushes, hedges and I'll probably dry brush some of it, but it looks good so far.
And now onto some features for the terrain boards - removeable trees and power poles. The beauty of these is I can stick them anywhere I like eg. the sides of hills, river banks, as part of hedgrows, in my opponent if he's annoying,

and then I can take them off for storage. I dont think they will damage the boards because the pins are pretty sharp.
Next I'll make some billboards and signposts. I have some square hollow lengths I'll use for the legs of the billboards.
Power poles
I got a couple packs of brass tubes (enough to make 30 + power poles) and marked the lengths and a pack of pins and chopped the pins up. I used the leftover pin head to fill to hole at the top of the pole, and the cross pieces are made from plastic card and rod. I'm making different styled ones with some have 1 cross piece and some 3 and a few with supporting brackets underneath.
I cut the brass to length and then used a dremel tool to grind some grooves into the pole (hopefully this will make them more robust). Then I glued the crosspieces in and then the pin head and sharp bit. I already had some strips of plasticard and rod cut up so I used those although the strips are too wide for the grooves

so i've been trimming them.
Trees
I got a pack of 70 Woodland scenics pine style trees (2.5 -4" tall) from the local model shop. Some of the larger trees I have chopped in half to make 2 smaller trees so I should get about 100 trees from the pack. Normally I'm not a fan of their trees but I got them so because I knew I could insert pins into the trunks without too much effort. The white fluffy stuff is packaging from Copplestone and Perrys figures, which you get in the little boxes they put their figures in.
You can see the progress from left to right. Find a tree, cut to size, drill a hole and glue and insert the pin using pliers, cover with glue and fluffy stuff. I'll spray these brown and then flock them and I'll drybrush the trunks a lighter grey colour.
Some more trees.
I had a couple of the wider Woodland scenic trees spare so I will give them the same treatment. I always find the WS trees dont have enough branches so I added some more from brass picture framing wire.
The last tree in the picture is a cheap chinese ebay tree. I untwisted the trunk piece of the wire and inserted a headless pin and twisted it back up again and then smeared some UHU glue on it.
Excluding forest and terrain pieces, I figure I need at least 10 trees per 2x2 foot tile, x 12 tiles per table = 120 trees!
Cheers
