Hi Reiner, can you post a .3dm file of what you currently have?

That would make it easier to give you some help.

Like Pilou mentions, it looks like one step is to focus on just one quarter of the design and then use mirroring to build the other parts.

Sorry about that, I thought you were asking about doing the central bubbly part, that's the part that zsurf could work well for, not for the knot work in this case.
