A multi-facet decoration assembly is provided, comprising multiple polygonal grates with equilateral sides. Each corner of the polygonal grate has one catch pin and one slot pin disposed on the underside. This unique decoration ball assembly can be easily assembled by snapping multiple polygonal grates together so that all catch pins and slot pins on all polygonal grates are locked against each other. The decoration ball can be easily stored away when the polygonal grates and the panels are knocked down occupying only a small space, thus the storage and transportation costs can be reduced considerably.
