Beehive Cake

Thursday was my mom's birthday but we are celebrating it today. Since she love Winnie the Pooh, I decided to make her a Beehive cake. I also bought her a Pooh figurine by Jim Shore. This was my first sculpted cake as well as the first cake I had ever made that was more than two layers. I had some trouble with the cake layers in the beginning because they kept wanting to crumble and lean. After I got the initial buttercream layer on and into the freezer it set up just fine and didn't fall over. I kept the cake in the freezer over night and today I covered it in fondant and decorations. For some reason my cake started sweating really bad. I had to put a fan on it after I covered it with the fondant to dry it and to keep my bees from falling off. The bees are having some trouble staying on still. I think they might be too heavy but I added a couple of toothpicks to help them out and it seems to be working for now. My only big concern is transporting it to the party tonight... My cake holder is not tall enough so I think I'm going to have to use a box. Hopefully none of the decorations will fall off. I surprised my mom with it this morning and she LOVED it. Of course I thought it turned out alright because I'm my biggest critic but she kept going on and on about how pretty it was and how much she liked it. :) Make all my hard work worth it. I would've had the cake finished a bit sooner (and with less stress) if I hadn't felt so terrible. Someone at work got me sick so I had to take a lot of nap breaks while working on the cake. But I finally have it finished and my mom adores it. She said she doesn't even want to eat it lol It's a chocolate cake with vanilla butter cream and marshmallow fondant.
Oh and if anyone knows the best place to get a cake board I would love to know. Lowes said they could give me a piece of plywood but couldn't cut it in a circle so I have no idea where else to go. Enjoy the pictures and any tips would be greatly appreciated!
