This is an awesome idea for making your own DIY Washable Big Game Bags!
We use California King flat sheets
fold them in half lengthwise, then stitch them together on both sides
What we have now is a full carcass game bag. I have used the same one on blacktail, pigs, mule deer, and elk. Washable, breathable and reusable.
Pillow cases make perfect quartering bags, with poly-paracord inserted as drawstrings.
