63 pounds of buttercream icing, fondant, cake boards, and cake decorating tools for my son's wedding cake in Las Vegas.
As carry on, 8 layers of cake [ranging from 14x14x2 to 6x6x2] carefully packed in custom boxes, that fit in the overhead bin.
The final 4 tier cake was created in a HGVC [the units behind the Flamingo] condo kitchen over 3 days and then transported by cab to the Palazzo.
