Saturday I bought some foam, flat white spray paint, and black sandpaper. It cost me just under $16.
I'm debating if I should start tracing out the dimensions yet, as they might change depending on what materials I get my hands on and what I can and can't do for the project.
And I'm also debating 'how' I should approach the sidewalk. If in 1:1 scale it's 6", in 1:64 scale it's going to be 0.09"! It's probably to minuscule to easily cut...hmmmm....
