I have a lot of corrugated card floating around from my materials orders and I needed a large shark model for the basis of a new project so I quickly scaled up the small shark model and cut myself a new one over 1m long (there is a join around the fin). It quickly enabled me to check that the scale is right and I can carry on building.
The blue foam is a different project again and came rolled up so this is the easiest way to get is flat for cutting again.
