The easiest way if you are going to leave the fur on is to;scrape all the meat off the skin,stretch it ou.I will take a staple gun and stretch it as far as I can while it's wet and staple it to a board.Then take 20 Mule Team Borax soap detergent and rub it into the skin side up while it is wet.Rub enough till its a thick paste.Then leave it in the sun to dry for a day or two and remove it from the board.Shake and dust the soap off and then rub it with mink oil.it will be stiff,but you kinda want that for a quiver.This is simple but it works.I've used it for a couple of quivers, including Otter skins.
