Wave vase : where to start?

I would like to try making this vase with grasshopper but i dont know where to start. Do you have an idea ? Is it better to have to create a surface and then project curves on it which will be extruded? or create curves by horizontal slices? I don’t know too much how to do it
Once I figure out the right technique to use I think I could do it, I’ve been practicing grasshopper for a few years.
Thank you.

Have a look at the attachment.
