Abstract: A plastic base form for creating conical-shaped, wire frameworks for decorative Christmas trees and the like. The form has a series of upraised channels and an aperture in each in order for a pin to be inserted in order to secure the wire members and then be removed when the decorative tree has been completed. The channels are arranged around the base into pairs. Such pairs are numbered in order to aid the user in constructing the conical-shaped wire framework when using this base form. Every other pair should be staggered to form two sets of channels, one set forming a small perimeter of about 12″ and the other set forming a larger perimeter of about 14″. Wire members, such as coat hangers, may then be placed in the channels and secured to one another in order to form the basic conical-shaped, wire framework.
