The fins were traced and redrawn in Corel Draw.
I knew for the rocket to be stable the fins would have to be larger.
Four different upsizes were made. I ended up using the next larger size.
The fins should be formed into a wedge shape.
I took the easy way out and simply "butterflied" them over cereal box cardboard.
The leading edge was scored. The underside got a thin coat of glue.
The leading edge was set over the straight edged of the cardboard.
All four fins dried in a heavy book.
