I was inspired by Basil's foam bluff on another thread but did not want to hijack his thread, so I started this one to show how I went from foam block scraps to this mountain tunnel.
After hot gluing all the pieces in, the carving started with only these tools.
I used the iron first to make my large marks and carvings. Then the hobby knife to scratch, slice an pick. A dull blade works best ( a good reason to save dull blades). Lastly rub hard with a metal bristle brush.
I added some foam pieces for more depth then painted all a medium/dark grey. I also filled some obvious foam lines with a plaster mix.
Now it's time to dry brush some white, tan, brown and light grey. The messyer the better. Then I made this nasty very watery brown paint mix and drizzled it in many places and let it run it's natural course. Use a drop cloth. We added some greanery and this is what we have so far. A log cabin will go on top.
My son and I had fun making a mess. Thanks Basil for your thread and motivation.
Have fun! Ron
