Well, I've not seen the movie yet (NOBODY SPOIL IT!!!) but historically speaking English archers didn't wear anything on the drawing fingers. No tab, glove or stalls at all. Yes, we're
that tough
:D
Medieval quivers were simply just cloth bags, usually worn around the waist. Sometimes worn vertically down the side, sometimes horizontally behind the back. The quivers were often fitted with a punched leather disc that held the arrows securely in place, but the cloth was soft enough that it'd pull the arrow in tight, yet let them be drawn when needed (Kinda like a well made back quiver does today)
