Radial symmetry is an option as well. The seams are challenging with stamp though.
I modelled the profile with primitives and used insert together with radial symmetry here:
I think @Holger_Schoenischka aka ProcreateFX made a tutorial on YouTube how to do it….well I would be surprised if not.
Edit:
Yes, radial symmetry. Don’t forget to uncheck the mirror plane in symmetry options. Use radial only and use a seamless pattern
