The best material to make a hay ring is a 16-foot cattle panel, a pallet, a tarp or tin roofing, rope, and four carabiner clips. Lay the pallet flat on the ground and position the round hay bale end-up on the pallet. Pull the cattle panel wire mesh around the hay bale and fasten the ends with carabiner clips. Cover the round hay bale with a tarp or tin sheeting and secure them to the cattle panel using a rope.
