Yea it might sound a little silly but how do i make a 3d graduation cap that will sit on top of a sheet cake?

How do i make it so that it will not sink in or something?

Ideas or tips are greatly appreciated

I'd make a little dome cake for the bottom part of cap, and for the mortar baord I'd use a bit of stiff cardboard covered with MMF or the like, so it's not so heavy. Put a covered button on top and hang tassle - should work for you!

Best of luck!

Here's one easy way: http://www.ktka.com/videos/2008/may/13/19666/

Jen...

there is a template here on CC. it is listed in the gallery under templates and patterns. I just used it and it worked perfectly!

thanks for the link!!

ness_p: if you look in my gallery I just did one.. it is blue with a white tassel. Here is how I did it... this is if you want an edible mini one to put on a sheet cake or tiered cake (as I did)

I took a standard sized square napkin and placed it over rolled out satin ice (or any fondant) and cut its shape with a sharp knife. Placed it on wax paper to dry (I put tons of powdered sugar on the surface of my cutting area so it would slide off to the wax paper.) I baked 2 layers in my wilton mini fill pans. I iced them with bc and let them sit until crusted then smoothed them with the Melvira method. My mortar board (square described above) dried for 4 days until it was stiff. I then placed it on top of the mini round cake with bit of buttercream beneath it. For the dot on the mortar board, I used a ball of smooshed satin ice. For the tassel I used Chocopan (a softer chocolate based fondant) and put it through a garlic press. You will have to keep adding chocopan or comparable product in small portions to your garlic press to get the length you want to achieve. I never took any of the tassel out of the press until I was at the length I needed... I then airbrushed the royal blue of the school colors and affixed the chocopan tassel to the hat. I hope this helps you out or is something some others can use! Good luck, it is easy!

and you know to use cake boards under the cap and a support system in the bottom cake.

The way I did it was I made a strip of gp about 3 inches wide and brought the ends together... I let it dry like that... measured how large I needed the mortar board and cut it out of gp.. let it dry for 3 days .. and put it together with gum glue

Awesome! thank you so much for your responses. and thank you sugarbakerz and cakebaker.... Your tips and ideas help me out alot!
