How to make a buttercream wave design🌊✨

As we say farewell to summer, here it is: the buttercream wave tutorial! This video will show you step-by-step how to achieve this cool effect! I hope it inspires you to try something new. :) How would you improve on this technique? Would it be quicker to apply the frosting using a piping bag for all the steps? Don't be afraid to frost the whole cake, I just did a base coat . It'd be cute to add other details, like fondant shells. I grew up near the beach and I really love watching sandpipers, so I had to add one on here. Anyway, try it out and let me know how it goes! Happy decorating!❤️✨
