Grandstand style flag

Experimenting with the terraces i wanted to make a kind of grand stand so it was easier to see the houses at the back.
Got the #lasercutter to cut and score a concertina flag book with an extra 0.5 cm on each.
It gives a pleasant outside that’s lined like a fan.
Practically it doesn’t make a big enough difference to give me the grand stand effect.
Here are the pix.
