HELP I am trying to construct a 3d chef hat like the attachment below can anyone please help me out with how to set this cake up

I don't see an attachment. I have a 3-D Chef Hat in my photos. I made it by stacking 7" rounds of cake filled with buttercream - cardboard between every 2 layers and dowels between every 2 layers. I then stuck 2 sharpened dowels through the top all the way through the bottom foamcore. Those provided stability. Be careful not to build it too high and allow it to get REALLY Cold. Hope this helps.
