ABSTRACT:
Disclosed is a method of making a multi-level assembly of flexible nets for supporting flowers to allow them to grow in straight, upstanding shape through the mesh openings of the nets which are raised progressively to different levels of height above a flower bed in accordance with the growth of the flowers. A plurality of nets are laid one upon another with their mesh openings substantially correctly aligned with one another and placed on a frame in a vertically zigzag folded pattern. Then, the nets are, together with the frame, immersed in a bath of a heating medium, such as hot water, to allow the nets to undergo thermal contraction, whereby the mesh openings of the nets are correctly with one another. The nets are, together with the frame, removed from the bath and allowed to cool. Then, the nets are removed from the frame with their folded shape substantially in order.
