While it is a bit of a comedic strip, it does provide some expansion on extended wing design. Originally had thought of opening up the centre to allow access for the pilot chute, but then thought it may be a bit too much wing disruption.
This woman's tutorial/walk-through on how she made her costume wings is *amazing*. Awesome creativity, and some pretty amazing engineering! Perfect for cosplay (I absolutely have to make a set of these wings)
