The above link will take you to the Sandals chapter from this very useful book written and illustrated by Brendan Smith in 1972. I have tried to contact Brendan Smith, but I haven’t been successful, as he has a common name. I decided to share the sandals chapter from the book, but if Brendan sees this and would like for me to remove it, I of course would.
This book has been significant in helping me learn to make sandals, so I am forever appreciative of Brendan and his work.
