I would color your royal (color flow) a pale gold color, sprinkle gold sanding sugar on top of the wet royal – it sets up quickly so do it soon after flooding. What I would do though is to roll out a sheet of 50/50 gumpaste and fondant – extra thin then take a brush and color the whole sheet with gold powder then cut out the area needed and paste it onto your grad cap with just a dab of royal. Don’t use Wilton gold edible powder. Does’t shine.
