I wanted to build a tunnel portal made out of cut masonry stones.
Shaywen developped a fine technique for building such a portal out of pink foam. It's described in the Academy - see this link. But I don't like pink foam that much, so I tried Robin's favorite material: Cardboard! Then I applied some of Shaywen's coloring techniques to it.
First I took a piece of stiff corrugated cardboard and cut out the opening for the trains.
Then I added the tapered stones (called "voussairs") which form the contour of the opening. The shape of the center keystone with its cover stone is copied from a photograph of a PRR tunnel mouth.
These 'stones' were cut individually out of stiff cardboard (shoe box). After glueing them around the rim I drew the lines for the masonry stone layers...
