After a year of wear my keys have made hole in my Lee BIB, so it's time for a repair.
I use a 12.75 oz lefthand Kurabo fabric with a golden selvage.
I cut away the weft threads from the hole and fold the edges.
Since the BIB is a righthand twill and the repair fabric is a unwashed lefthand twill it might be some nice effects after I wash the BIB again.
Done!
