Be practical, waste nothing.
Save the eyes to see the unseen, to have visions, and dream dreams.
Preserve them and keep them to see like the animal and better shift your shape into feather, fur, or silver skin.
Eyes to spy. Wear them around your neck or place them under you head to see through the eyes of their living kind far away.
Eyes to send the evil eye. Eyes to bind and blind. Eyes to stab and curse.
An eye to repel the evil eye. Add to a protection talisman to carry or hide in your car or home.
Eyes to watch and warn of dangers. Hang over your door for the worries of this world and place on your altar for dangers from the otherworld.
Eyes as offerings to seer spirits and deities of the divinatory arts. Burn them, bury them; the eyes to see your future.
To dry, cover in salt or cornmeal (or a mix of both) in a bowl or wooden box (nothing air tight) for a few weeks to months depending on the size of the eyes. Remove and clean off particulates with a dry brush. Keep clean and dry to preserve longer.
You can also soak them in vinegar in the fridge for a few days and then oven dry on low heat with the oven door kept open with a wood spoon to let out moisture. They become eye jerky – keep away from hungry cats and dogs.
Add to crane bags, medicine bags, or spell sachets. Craft into talismans – stitch into a leather pouch with herbs. Store in ziplock bags if to be stored for later use in nitty-gritty folk magic. To “re-animate” for magic, soak in room-temperature water for a few hours.
Vegetarian? Sew, embroider, carve, or sculpt eyes for the same magics (I am now picturing an angry vegetarian stabbing a clay eye with a toothpick).
