I'm delivering a two tiered hexagon barn cake tomorrow and the party is not until Sunday afternoon.

Should I buy a regular shipping box and line it with foil? If I can find one big enough to place over an 18" round?

I buy new boxes, for this a 18x18 (or 20x20 with a non skid mat)

I put the bottom of the box together using strapping tape, put the box on its side so it opens in the front.

the cake can slide it, and it is easy to remove it.
