The legs on this model are a single layer of thin card. This presents a couple of problems. Firstly, it looks flat, unlike a real leg, secondly as the card is thin the piece is what we paper engineers call 'flappy'. It flaps around and curves up in the wrong direction.
So – before gluing the legs into place I have given them a gentle curve in the vertical axis. This has the twin benefits of having a realistic 3D look and making the legs stiffer. Hopefully you can see the effect in the photo.
More web work this evening then back to the scissors tomorrow.
