Thank you K8memphis!

i'm gonna guess 12x9x6 -- at least 3 inches between tier sizes

Thank you again K8memphis! I was kind of thinking the same thing.

Another question if you don't mind; would you use a toothpick to make the birch bark marks a initials carving or something else?

sure -- i think i would first try a sharpened 1/4 inch dowel that the point was blunted out on -- it looks like a bit bigger mark than a toothpick -- or maybe a skewer -- i think a shishkabob skewer would work good too - or even the side of a fork tine --

i'm not sure how i truly feel about barbed wire on a wedding cake but it certainly was done well -- beautiful cake -- 

Haha! Well, actually the bride didn't like the barbed wire either...but yes, they did it tastefully!

This is going to be a personal cake for the bride and groom, and she wanted it to look almost exactly like the picture. Since it is kind of big though, I was thinking of suggesting smaller size tiers. If I made it 10", 7", and 4", do you think the top tier would look too small and funny?

so long as she knows it will be a petite cake i think it will be awesome but she probably does because you say it is a 'personal' cake -- are you doing the figurine on top?

margaret braun in her book cake walk routinely makes 4" top tiers that are 4" tall she even has a 2" tier that is 4" tall on page 124 in her 'all about the bows' cake -- you're in good company --

and fwiw i've never seen barbed wire that wasn't rusty :)

Thank you SO much for all your help K8memphis! I feel more prepared now!
