I let myself be talked into doing a topsy-turvy cake for an order due at the end of the month. It's a Halloween-themed birthday for twin 4-yo boys. It will be just 2 tiers.

I don't plan on shaving the sides of my cake, just the top at an angle. I printed out the instructions here on CC, but was hoping some experts had some suggestions / tips they could share with me so I don't mess this up?

It will be covered in bc with fondant / gp decorations, as well as bc decorations.

Thanks!

After the first (and only) one I have done, the only advice I have to offer is get some good rest and then tackle it. Take your time with it. The instructions are a dream so you'll have no problem there.
I can't wait to see a pic!

I followed those instructions for my first and I continue to use them for all of my topsy turvy cakes!!! The directions are great and they work! I think it looks nicer with the sides shaved down but I guess it's not a MUST...gives it a more tipsy appearance though.
My advice to you is give yourself at least 5 hrs. more than you think you'll need. The first one I made turned out alright, but I spent hrs just trying to get the frosting perfectlly smooth lol Now I can crank the whole cake out in a couple hrs.!
