How to build a 15mm stone wall

First things first is get your supplies together.  I use the Poultry Grit as the stones because it was cheap and available.  It also has nice angular pebbles which make nice looking finished wall.

I just lay down a thick layer of white Elmer's glue, which I believe is the same as PVA glue, but really have no idea.  After I lay down the glue I start by laying in a nice layer of pebbles. I let the glue dry some between layers of pebbles as it just makes it easier to work with.

After the first layer is dry I lay down another layer of white glue and keep gluing the pebbles to the wall.  This took most of the day, but only because I would let each layer dry before I started gluing the next layer.  

Once the wall is done it is time to do some painting and dry brushing.  I bought some super cheap craft paints for this at Walmart.  They cost $.57 per 2 oz. bottle.  I got pavement grey (dark grey), pewter grey (medium grey) and a bottle of white to mix with the pewter grey for the lightest layer.  Also get a cheap flat paintbrush for the painting and dry brushing.

First put a nice cover of the dark grey all over the stones and base.  

The last step is the dry brushing.  The quick and dirty explanation of dry brushing is to put a little bit of paint on the brush and wipe it off on a paper towel by "painting" the paper towel until you don't leave any paint marks.  Once this is done dry brush the stones with it.  It takes several layers of dry brushing  to get them to look like right, but the final effect is really nice.  I dry brushed first with the pewter grey then I dry brushed with a 50/50 mix of pewter grey and white.  This process goes quickly because there is so little paint that it dries very fast.  Also make sure that your first coat of dark grey is dry before you dry brush or you will have a big mess.
