Do you make your own cake boards out of plywood? If so, what thickness do you find works best?
TIA
I make my own too! I layer thick cardboard pieces and cover them with tissue paper, and then celophane so it's food safe.
I use pre made vardborads for standard sizes but for custom sizes or really heavy cakes I use 3/8" pressed board, I buy it in large sheets & my husband cuts them for me as I need them.
Back in my bakery days, my hubby would make any custom-sized boards from 3/8 - 1/2" plywood. I had quite the collection when I closed the shop! 
Now when I do a wedding cake here and there, I make my own from several layers of foamcore board. I also buy the cake drums from CK Products for my sheet cakes and sometimes for the base boards.
