This is a 3-tiered cake for my grand-daughter's 7th birthday. Most of the decorations are between the layers in the separator plate areas. I used flexible Plexiglas painted with shimmering acrylic paints in shades of blue. Then I scored and cut the Plexiglas into jagged pieces. I attached them to the lower separator plates with Royal Icing. I put blue flickering tea candles (battery operated) inside the ice castle so the blue looked even more like shimmering ice. I added Frozen figurines, a pond, a clear wedding staircase and some snow covered trees to decorate the presentation board. It was a big hit at the party.
