Looking for helpful hints on getting this technique down. Know of any tutorials? Looks like something is just dragged around the outside..maybe the spatula, or a tool. Thanks.
If it was me I would just ice a cake, kind of smooth but just spatula smooth. Not viva or roller smooth. Then I would take a knife with a point, balance my forearm on a box or something to stabilize it a little and give the turntable a spin, pushing the knife point in a little then gradually go up. Or down depending on if you started at the top or bottom. Just my guess, anyway.
Interesting that you posted this, I just watched a video on this very technique yesterday. It is from a fellow cc'er; costumeczar. She has several youtube videos that I have found to be helpful. (Thanks costumeczar!)
