OK, the project is progressing--
Here's a "tool" that I made so I can quickly measure the gaps for the hallways. I made a 2" and 1" space. You can place the gap across the gridlines and draw little tick marks. Then you can freehand the walls on the tile. I also made a 4" rule with a 1/4" tick mark for quick use.
Here are a few tiles drawn in -- I want to try a proof of concept before I finish the whole thing. No sense in wasting time.
I used strips of black foam for the walls. They are flexible and irregularly shaped. It's kind of an eggcarton foam that I get from work (electronics packaging.)
Now I've covered the foam and tiles with TP using a glue/water mix. About 50/50.
Gonna let it dry. Then I will cut out the tiles and spray paint them black.
We'll see how it goes!
