Klövjesäck is stitched in a really rough linen. Two equally large, peanut-shaped pieces. In one of the two openings made. Then they just stitched together. Just make sure that the seams on the bottom of the bags are sturdy, because if you wear heavy, they can crack.
The advantage is that when you have it over your shoulder as you turn inward openings and keep a hand around the part that lies ahead, and then it becomes almost impossible to steal something out of it if you go to a market or something.
