I am replicating or attempting to replicate a topsy turvy wedding cake and the original cake board is white, it's not covered in fondant. its smooth, white and has little crosses on the edge. I'd like to know if anyone knows where i can get these, i've tried where i get my baking supplies and online. NOTHING!!! someone pls HELP!!!!

most likely it's a white foil cake drum

Try googling "white cake drum" and see what you get! There are millions of places to get them and generally they'll be a couple dollars each1

( I have and all i get is the white floral cake drum..... i'll keep trying i still have 3 weeks to go.... I feel like crying
Thanks so much for your help.

I can't tell if you're looking for white drums that are embossed with textured foil or if only smooth will do. Try Viking Imports http://www.vikingimporting.com/index.php?cPath=146&osCsid=84d31a29d7470da92f995900a05a25d6 if this is what you're talking about. Otherwise, you could use multiple cardboard circles taped together for the thickness needed and cover with plain white wrapping paper or freezer paper. (since the wrapping paper isn't foodsafe, you'll need to have your cake on its own circle so it won't actually be touching the wrap.)

can you share the ones you're talking about OP?

little crosses on the edge? Like grosgrain ribbon perhaps? You could take 3-4 waxed cake boards (smooth, white, and shiny) and glue them together and then glue the white grosgrain ribbon around the edge. I love that look.

do you have the photo of it?? that would help a LOT!
