Method of covering a pot or floral grouping with a sleeve having a triangular lower end

A method of covering a pot or floral grouping, comprising:

• providing a sleeve initially constructed in a flattened condition, the sleeve comprising:
• a body having an upper end, a triangular lower end, a first sidewall edge, a second sidewall edge, and an inner space and further comprising a lower portion and an upper portion extending from the lower portion, the upper portion detachable from the lower portion via a detaching element, the sleeve in the flattened condition having a terminal vertex in the triangular lower end at a junction of the first sidewall edge and the second sidewall edge, and the terminal vertex having a terminal vertex angle which faces inwardly and has an angular dimension greater than about 30° and less than about 160°, and a portion of the first sidewall edge having a first vertex, the first vertex having a first vertex angle which faces inwardly and has an angular dimension greater than about 100° and less than about 165°, and a portion of the second sidewall edge having a second vertex, the second vertex having a second vertex angle which faces the first vertex angle and has an angular dimension greater than about 100° and less than about 165°, and wherein a lower segment of the first sidewall edge, a lower segment of the second sidewall edge, the first vertex, the second vertex, and the terminal vertex cooperate to define the triangular lower end, and the body of the sleeve having a generally tapered shape when in an opened condition;
• opening the sleeve to expose the inner space of the body;
• and
• disposing a pot or floral grouping into the inner space.
