ok...so i've stacked 3 layers before...can i do 4 (2") layers without separating with a board? my dilemna....i stacked 3, 10" squares already filled and then realized maybe i need another layer to improve the look. i'm wary of stacking another layer on top. has anyone stacked 4 high without problems?
oh..btw, i'm just making a box so i wont have to put anything else on top.
Depends on how sturdy and heavy the cake itself is.
Well, the general rule is a board every 4 inches.
I, personally, wouldn't do it, but I also torte and/or fill every cake.
I "guess" that if the cake is a really dense, sturdy one (i.e. pound cake) and only buttercream is being used to hold the layers together, it might be OK.
I wouldn't do it. Every four vertical inches you should put in support.
Definitely need support & board for every 4" of height.
