I've been making a bit of terrain. This happened by accident. I went to the hardware store (Bunnings for those Australian readers) to get some cork tiles to make some Stalingrad type ruins and walked past an outdoor door mat on a shelf. It was brown and had really prominent ridges.
So, I bought it for $8.00 and took it home. I cut it into pieces, did a bit of dry-brushing in a lighter shade of brown, dabbed on some pva glue and added some flock. within a bout 30 minutes I had a bunch of cultivated fields. They're a bit too neat but adding some fences and hedges etc, on the table with them will fix that.
