One day in advance, make fondant topper.
Tint fondant yellow, orange and red following color formulas above. Using 9 in. fondant roller with pink guide rings, roll out fondant colors, separately, 1/16 in. thick. Cut designs using desired fondant cut-outs. Use smooth side of “A” size round cut-out to cut circle base. Use scalloped and smooth sides of leaf cut-outs in varied sizes. Use mini cut-outs to cut flowers and leaves.
Use damp brush to attach shapes to circle base, layering some flowers and leaves. Let dry overnight on cornstarch-dusted surface.
