Abstract: Disclosed is a crown which is essentially a single piece unit formed desirably of plastic having a domed center portion with a plurality of guides, and depending sides, each of which has coordinated guides. The sides, in turn, are hingedly secured to the domed central portion to permit a dependent relationship. Because each side has a securement means for penetrating a foam block, they can be wrapped around such a foam block in anticipation of the insertion of the decorative elements. Further in coordination with the crown, patterns are provided in which a sizing discipline is shown, and with exemplary head sizes, to the end that flowers, whether artificial or natural and items such as flags, balloons, hearts, signs, or other emblems, can be sized and then directly inserted into the crown in accordance with the keyed indicia on the sizing portion of the patterns.
