This is a leather three ring binder I made on commission. It has oak covers bound in deerskin, three ties in the center for holding paper, a leather flap to protect the pages and a braided nine strand waxed sinew tie. the bookmark can hold two places and has toggles made of sheep knuckles (roman tali).
All in all I'm rather happy with it and the gift recipient was very pleased.
I should make one for myself now!
