It seems like you can never have enough hedges or trees in your medieval or ECW games and although I have several feet of hedging I only had three trees. By adding 6 more I have tripled my collection!
2 of them are made from Woodland Scenics armatures, 4 of them from sage brush cuttings I bought second hand; on some of them I added plastic WS branches added to them as shown in the picture below:
I used my now go-to material for the canopy branches, 3M Heavy Duty Stripping Pad material.
After a spray coat of grey primer, followed by GW's Wyldwood contrast paint and a light drybrush of grey foliage was added.
I used two types: on your left in the photo below, Heki Tree Leaves 1620 and on your right, a blend of SuperLeaf med. green and spring green (with a pinch of moss green).
The basing is my usual static grass mix with med. green SuperTurf and home made shrubs over a foundation of bark mulch that had been ground in a coffee grinder. With a coat of thinned burnt umber I am quite happy with both the texture and colour.
