Just thought I'd post to show my set up.  This is the attack on the Austrians at Abensburg.  The French are standing in for Bavarians in this battle.

I use a modified Lion rampant set of rules where each unit is a brigade of infantry or cavalry, an artillery battery or regiment of skirmishers/light infantry.  Infantry brigades have four bases each 50 by 10 mm.  Artillery are 25 mm wide with a limber and gun.  Cavalry are two bases each 50 by 20 mm .  Skirmishers are two bases each 100 by 25 mm.  Each base is 3 strength points.

Ground scale is roughly 1" equals 100 yards.  I can't fight Wagram at this scale but most other battles in the 1809 campaign are do-able.

Very nice,love the look. Gives me a feeling of wish I was there to game that.

Looks beautiful! What did you make the trees from out of interest?

Thanks guys.  The trees are made from upholstery foam died green with craft paints, blitzed in an old blender then glued to hanging basket liner which is itself glued to 1" mesh.  Individual trees are just bits of that foam impaled on a variety of nails.

Completed forests:

The forests look very nice, as well as the battle proper! What kind of glue did you use for attaching the foam? I've tried making similar stuff using both hotglue and PVA but the former takes a lot of work (as well as copius amounts of gluesticks), while the latter doesn't seem to hold that well.  

I use Evostick wood glue - which I think is some type of PVA.  It takes a little while to dry but holds OK once done.  I've tried it neat and watered down and both seem to work ok.  I have found that the edges have to be done one at a time to let the glue dry or the foliage falls off whilst you're trying to cover the next.

I use a slightly different method. I use black foam board for the centre. Painted fat stick pins are used for tree trunks. The foliage is simply glued on top using basic white glue. Some fall off with handling but is a quick fix. 

My experience with that Glenn, is when using commercial foliage which is more 'stringy' for a lack of a better word, PVA and hotglue seem to work fine, albeit slightly differently. With these kinds of spongy materials though the PVA doesn't seem to hold that well, maybe I just need to use more initially or add a heavier watered down coat on top of it all after drying...

Mine have actually held up pretty good. I made a couple a few years back and have only made one repair. That's probably because they are actually rarely handled. I use them more for woods that are not likely to see any action. 

I guess that might also be it, I tend to use these canopied woods as the ones that can be moved away/around if/when models enter wooded areas, while woods based on larger pieces of mdf tend to stay or only be nudged slightly to make room.
