Shed covered with straw After the sunset, cover the grass curtains on the sheds until the sunrise. Connect the inner side of the grass curtains with rushes or straw, and connect the reeds on the outside with a cover of 0.04 m in thickness and 2 m in width. It can also be covered with straw straw alone to enhance its insulation.
