There's Wall - DOH!
As I begin to prepare the table for our next Frostgrave game, still a few weeks off, I was laying out my buildings & thought, there just doesn't seem to be enough terrain to block archers from shooting across the board.
Then I began to think about alleys, a harbour, etc. So how do I create an effect of raised areas with cobblestones, & stone walls easily.
Some time ago I had managed to save some pink foam from going to a landfill, asking the guys on the site if I may take some of their scraps. It's been stashed away for the most part.
Taking a larger piece, I decided on a size & keeping it simple for my test, just created a rectangular piece with a ramp to allow wagons to reach it.
Then I had the issue of how to make a pattern (which wouldn't take me all day)
I then remembered the cobblestone/flagstone rollers I got from Greenstuff World.
