If you ever owned a pair of Edward Green Dover's or one of their many hand-sewn apron shoes or boots there's a very good chance they were sewn by this man.
Andy is the head, master hand-sewer at EG. It's a real treat to watch him work, besides the fact that he's a great guy.
The hole is made with an awl then the thread is passed through attached to a boar bristle. It's slow going, producing about six uppers a day, with nil margin for error.
Something to consider and appreciate next time you put on your shoes.
