Abstract: A garden cloche is erected by folding an elongate sheet of transparent plastics material along crease lines preformed in the sheet. These crease lines include a central longitudinal line and at least two outer longitudinal lines permitting the sheet to be folded to form an inverted V shape with watering troughs along the bottom of the roof-shaped sides of the cloche. Moreover, lateral crease lines extending between the central longitudinal crease lines on a zig-zagging outer longitudinal line on each side of the central line alternate in length so that upon folding the sheet, the panels defined between adjacent pairs of crease lines are alternately inclined to one another producing corrugations which strengthen the sides of the cloche.
