plywood cake boards how thick and where do u get them from? also big should it be from the base of the cake?
You can get plywood cut to size at home improvement stores. Most cake boards are 2in bigger than the size of the cake, larger if you want more base board to show for decorative reasons.
I would imagine that 1/2in thich ply would be more than thick enough for even the heaviest cakes.
I was looking at the pre-cut circles today at Home Depot and they were probably 1in thick w/routered edge--very heavy. They would make a great display stand but I think I would still put the cake on a drum or cardboard. I can't imagine moving a cake around on that for decorating, etc.
Your Cake supply shop should carry them. If not a local hardware store will cut them for you. They should be no thicker than a regualr cake board.
By the way, instead of plywood, I think its partical board which is the same as pressed wood.
Treat these boards the same as the cardboard cake boards.
FYI, they are pricey, for that fact I get a deposit on all mine.
