This could be used for any cake, it would be extra nice as part of a season gift-cake for the christmas season. You could do a christmas tree shaped base for a christmas tree shaped cake :)
we let it cool a little and realised that we didn't have a platter to ice the cake on, so I went to work on making one.
> cardboard at apropriate size
> scissors (or knife) to cut cardboard
> aluminium foil (aluminum foil will work too)
> tape to secure foil
> a cake to ice (it would be pointless without one)
