Before covering the pottery, consider wrapping it with insulation material to provide an extra layer of protection. Use burlap, bubble wrap, or specialized frost protection fabric to cover the exposed surfaces of the pottery. Secure the insulation material in place using twine or fabric ties.
To shield the pottery from snow, ice, and freezing rain, cover the grouped or individual pieces with a waterproof tarp or heavy-duty plastic sheeting. Make sure the covering extends all the way to the ground to prevent moisture infiltration.
Fasten the tarp or plastic sheeting securely using bungee cords, rope, or weights to prevent it from blowing away in strong winds.
