ABSTRACT:
A method of fabricating model trees and plants for decorating a diorama. The model is made from stacking foliage disks on a telescoping dowel, which functions as an imitation trunk. First, an outline of leaves and branches is drawn within a panel on paper. Next, the outline is shaded in to obtain a silhouette thereof. Numerous foliage disks can be clustered on a single panel to conserve space and to facilitate mass production. The silhouette is photographed to obtain a reverse image. Then through photolithography and etching, a metal template of the reverse image is made. The template is overlaid on a wood veneer having a kraft paper backing, and is laser cut. After laser cutting, each foliage disk can be separated from the veneer sheet. An assembly hole is provided in each foliage disk to facilitate attachment to the dowel. In an alternative embodiment, the trunk can be fashioned from braided wire with one end that is unraveled and flared outwards. Individual foliage disks are then mounted to the flared strands. A modelmaker can customize the model trees by painting the foliage disks, bending or shaping the foliage disks, cutting the dowel or braided wire to obtain a certain scale tree trunk, or using different wood or paper veneers from which the foliage disks are cut.
