Step One
To start adding texture, I simply apply white glue directly to the base. For
multi-model stands, this usually involves a stripe across the front and
generous 'dots' between each model.

Step Two
With an old brush, spread the glue as evenly as possible, abviously trying to
avoid getting glue on the feet of your models. I dip the brush in my water jar
and touch it to my paint rag - the wet brush makes it easier to spread the
glue around, but too much water makes it run and weakens the bond.

Step Three
I think one of the secrets to great looking bases is using a mixture of
textures. Whether basing models singlely or in vignettes, I always use two
different materials. One is a medium ballast from Woodland Scenics made
of nearly uniform granuals (back) and my secret terrain making material -
coffee grounds! The latter is made up naturally of many different sizes of
'nuggets' and looks more natural than the more uniform ballast.

Step Four
The coffee grounds go on first. I dip a corner or side in the bin and shake
off the excess. For multi-model stands, try to carry the texture across the
unit. Whe you place the unit in it's most commonly deployed formation, you
want it to appear as one big stand. This is hard to describe so I've included 
a handy diagram below!

Step Five
From the coffee ground bin directly into the ballast!

Step Six
Shake off the excess and set the base aside to dry.

Step Seven
On to painting! If your texture is cunning chosen, there is no need to base
coat it. The natural color of my materials works great with my terrain so
all I need to do is add highlights. I use Foundry Base Sand Shade (10A)
for all of my bases, but what you choose should depend on your terrain. The
paint is applied with a heavy drybrushing technique.

Step Eight
Time to add details. This step can easily be skipped, but since I'm writing a
tutorial, I thought I'd go all out! You can add all kinds of battlefield debris,
fence posts, etc. For this unit, I'm just going to pick out a few stones in
grey to match my terrain. These are done with the classic three-step Foundry
method using Slate Grey (32A-C). I simply pick a few of the larger grains
of coffee and paint them as rocks.

Step Nine
Depending on your terrain, you might be finished. My unit is going to be
normally deployed on my grass terrain boards so I want keep going. A little
glue goes a long way with static grass and each stand only gets a drop or
two because I want all of my hard work with the initial ground work to show.
Again using a wet brush, spread the glue in patches. I use a diagonal
pattern to break up the square bases and stipple a few spots unconnected
to my main sward to give a more natual appearance. 

Step Ten
Again, in multi-stand units, you want the grass to carry across the unit and
again,  this is hard to describe so there is another diagram below.
Simply dip the stand in a bin of static grass or flocking and dump off the
excess. You can add small clumps of shrubs, long strands of yellow grass,
or any other details you can think of.
