I want to offer 6" "drip" cakes for Valentines Day.  Since they will be so tall with the top decor, they won't for my regular boxes.  Any ideas on clever packaging?

Have you checkout some of those shipping boxes? They are heavy duty and you can get them in just about any shape and size. :)

I usually use shipping boxes as well. Sometimes depending on the client and the cake I will cover the inside with parchment paper. But they tend to work out well. Great for long car trips.

For all of my taller cakes, I  use brown corrugated  shipping  boxes from WalMart.  They're  less than $1 and come in a variety of sizes that accommodate  cake boards beautifully.   I assemble the box amd tape the bottom, flip it over and slice the 2 corners of the front of the box so it folds down as a flap.  I place the cake inside, put the flap back up and wrap a few pieces of packing tape to secure the area that I cut.  Works like a charm.

I do the same exact as @oftheeicing  and I agree, works like a charm :)

Thanks for all the answers!  I'm thinking more of a "gifty" look  I've decided to use an 8x8x5 cake box with lid removed then wrap the whole thing in cello and tie with a bow.

suggestion -- why not keep the security of the lid -- if you cut a little slit in the top edge of the box and/or the bottom edge of the lid you can firmly affix it so it stays open and provides important coverage/protection-- just a thought

best to you

Good idea!  Thanks!
