PROBLEM TO BE SOLVED: To prepare a cover sheet capable of easily and surely circumferentially covering columnar bodies standing close to each other at any intervals. SOLUTION: This covering sheet is such one that slide fasteners 2 are provided to fasten the mutual division sides of divided sheets 1a disposed so as to sandwiching three tree trunks 5a, 5b and 5c, six openable sliders 3 for opening/closing the fasteners 2 are attached to the fasteners in an alternately reversed manner, and the sliders 3 are advanced one by one forward from both sides of the respective tree trunks 5a, 5b and 5c to close the fasteners 2 to the ends, thus easily and surely circumferentially covering the respective tree trunks 5a, 5b and 5c.
