Without having any real concept of how to make the walls, I picked out the materials that made sense:
* PVA glue.
* Medium size tallus I use for basing.
* Small popsicle sticks.
My initial idea was to mix PVA glue and tallus into a thick grout and spread it across the sticks. This turned out to be a completely impractical idea – the stone/PVA glue porridge stuck everywhere but where I wanted it to, but mostly to my fingers.
It was time to regroup. Next, I cut up the sticks into smaller bits and then put a thick wad of PVA glue across their length. Then I just strossled the tallus into the glue.
This approach seemed to work much better, but the ‘wall’ seemed a bit low with just a single layer of tallus. So I waited an hour or so and then repeated the process – I put another blob of PVA glue on top on top of initial layer and more stones were sprinkled on top.
Also, just to make the ‘wall’ a bit more compact, I squeezed the stones together a bit. With the first layer semi-dry I had actually a bit of control when shaping the wall.
I left the walls to dry over the night. I was a bit concerned about possible warping, since there was a lot of PVA glue pulling at these sticks from the top. But, possibly due to the fact that the wood pieces were no longer than 10 cm, they stayed flat.
Painting process started with an overall black coat.
Next, I drybrushed the walls with successively lighter shades of grey. Here’s the final result (althogh I did flock the bases with some green turf).
The entire project took me less than two hours to complete. It’s nothing complicated, but I have to admit that I was surprisingly pleased with how those little walls turned out. Mostly because it was a true scratch build and I don’t do those very often.
I used a similar technique but using cat litter and a coffee stirrer glued to the stick so it looks like an inverted T. Then I did much the same as you except I had a central base to build on. When both sides of the wall were dry I put another layer of pva and cat litter along the top. And finished off the same way as you. You can get a big bag of cat litter for far less than the talus.
