My brain-tanned nutria pelt murse. Case-skinned. Stitched the bum side with my bone awl and brain-tanned buckskin thong. The opening is where the face is, the shoulder strap is looped through the fore arm holes. Shoulder strap is a 5 strand braided chem-tan deer hide from scrap bins. I have only made one cut around the base, other than that the hide is in tact in case I want to use it later for a jacket or something.
