I was wondering where I could purchase either from the internet or from a store, some sturdy and thicker cake boards. The only cake boards I have found were those really thin cardboard ones that barely hold the weight of my cakes. I am afraid to order off the internet because I am not sure of their thickness. Also I was hoping to find ones that are as cheap as possible so I didn't have to ask customer's for them back. Cardboard is fine as long as it's thicker, I can always put decorative foil on it. Also if anyone makes thier own and would like to share, I would really appreciate it. Thank you!

If I have a heavier cake, I just double up and use two cake boards, or three if need be and I don't have to worry about getting my 1/2" drums back. Works great! I just stack them and cover with my foil and don't ever have any issues. HTH!

Buy the 1/2" foam core boards at michales and ac moore, etc. I think some dollar stores have it. Cut it with a box opener, some use x-acto knifes, some electric foam cutters,etc. Many on this site do this same thing. I buy the 3/16" thick also. so check this out. I use them alot.I think they come 20"x30" and then the different thickness.

They're called cake drums (thicknesses are specified on the sites):

or you can make your own using foamcore or several thicknesses of corrugated cardboard covered with colored foil, but keep in mind that colored foil might not be foodsafe which doesn't matter as long as you're placing each cake on its own corrugated cardboard anyway.

Don't ask for cardboard cake circles/drums to be returned... they are disposable. Would you like it if your favorite pizza joint asked for you to return the cardboard circle so they could re-use it again?

Stack 3 boards together, alternating the grain. Tape them together with masking tape all the way around and then cover with paper, foil or fondant.
By alternating the grain the boards are stronger and are less likely to bend under the weight of the cake.

Thanks everyone, great advise!!

i love the ones from BRPboxshop.com The silver or gold foil ones i use for my bases, and then i use the white one when i'm stacking tiers and they won't be seen.

Kelly, we get some of our boards 1/2 sheet, from SAM'S club. Go to the bakery and they will order them for you.

For 3 tiers and less, I just take 4-5 of the regular cake boards, tape them together with the grains alternating directions...and then its a nice thick board to wrap, and quite sturdy.

For more than 3 tiers I order the Nova wood boards from Oasis Supply (they are local for me)...they are a very sturdy thick wood board and they are like $10 but then if I'm doing a 4 tier or more cake, the price of the cake pays for it and I don't need to ask for it back.

For odd shaped boards I cut the 1/2" foam core. The big candy Bat Mitzvah cake I just did, I doubled up foam core so I had a 1" base for the heavy cake.
