This post came from looking through a few class photos from Rabbitstick several years ago based on an inquiry. This is one of the years I taught my favorite sandal design, an ancient one though still cleverly marketed as a modern style.
I call them saint sandals as they look like something you would see on a medieval depiction of some holy wanderer from Europe or the Middle East. To me, these are the greatest sandals I have ever owned.
This design is a good introduction to leather working and specifically, making footwear, which can be a bit more complex than most people know. Shoes really need to fit well in order to not cause pain or damage to the feet so an open design is a good way to start on this craft.
As I make them, the sewing is fairly minimal and can be eliminated entirely with the use Barge Cement. The sewing makes them a stronger design and I think adds a sense if beauty and craftsmanship to the final product. It is also a good introduction to double needle saddle stitching.
