I was searching for stand up pvc cake structures and found this structure to make santa clause on sugarshack's site.

There is a white board/disc with four holes where the body of santa (cakes) sit on. Could someone please help me and let me know what is this board called? I thought it was a wilton separator board but the separators don't have holes in them. thanks

Well I can't say for certain, but I've seen this technique done before -- it could just be a cake board (drum) with the legs screwed into it. That's what it looks like to me. But I would suggest writing to Sugarshack and asking her -- she's very helpful, she'll answer your questions.

Further down it says it is an acrylic plate... where you get it or if it is a specific cake acrylic plate I have no clue, lol.

I think that is the stand Bronwyn sells on her website. cal ja va on line . com/ cakestudy (take out spaces to enter website)
The cake sits on an acrylic plate that slides onto the stand.
