To make it possible to arrange flowers at desired points and angles by molding flexible materials to a slender and roughly metallic wire shape and a spiral shape by using synthetic resin blanks, integrating the desired amt. of these flexible materials and entangling these materials to a state complicating each other and molding the materials to coarse and dense massive materials.

The flexible materials 1 formed by using the synthetic resin blanks and molding these blanks to the slender and roughly metallic wire shape and the spiral shape are separated to suitable amts. The separated flexible materials 1 are integrated and are entangled with the inter-complicated and random state. The materials are then press fitted into a molding flask of a round shape and a weight is applied thereon. Hot water is put into the molding flask to deflect the blanks and, thereafter, the materials are cooled and molded to the coarse and dense massive materials 2. The materials are loaded into a vase and are used as a flower supporting member for flower arrangement. The curved supporting members of this flower supporting member for flower arrangement are entangled with each other as many pieces of curved supporting arms and, since the members have moderate gaps, elasticity and universality, the arranging of the flowers desired to be arranged at the desired points and the desired angles in the extremely stable state is possible.
