I purchase a corraguated cake boards, and for my opinion, they look not sturdy to support cakes, between tires. Are you using one or two glued together? I am worry that two boards will make big space between cakes, when stacked.
Also can cake base support 3 tier cake (14,10,6)?? Thank you.
I have not had any problems with a single cake board supporting a layer. As for supporting a multi-tier cake...a single-thickness board isn't the best for that, IMO, but a cake drum seems to work just fine.
Cake drums work great, but they are expensive! I have been taping several cardboard cake boards together and using that for my cake base. I haven't had any tiered cakes transported that way but the single layer cakes seem to do just fine with two cake boards taped together.
I would say it just depends on the weight of the cake. I have used single cardboards, I have used double and triple. I have used cake drums. I have gone out to Lowe's and purchased a round bar stool top (sold separately without the legs). And I have used masonite boards. Masonite boards are nice because you can reuse them...they are pretty cheap and they can support quite a bit of weight. Hope this helps!
