I made fins for my model rocket project from 2mm plastic. I rounded all the top edges and sanded a blade like edge on the bottom to get an airfoil to minimize drag. All the surfaces are finished with water sanding up to a 1200 grid paper so they are very smooth.
Motor mount and parachute material can be seen in the bottom middle photo.
