how to make this texture like this?

I don't know what's wrong with me either 😉
My comment was not aimed at you personally and I had no intention of attacking you, particularly with my last post. That the projected curve has such terrible curvature is not your fault and the technique you demonstrated is solid. However, this is an area where the Fusion 360 team needs to do some substantial work in order to improve the behavior.
There is a reason I had asked you to make a screencast. Yeah, I can see you rolling your eyes, but let me explain where I am coming from.
I have some 16000 posts on the Fusion 360 Forum and over 1700 solutions. Something I've learned is to read a user's level of experience and gage what is needed for him/her to succeed. It was immediately clear to me that your brief message would not be enough explanation for this user.
Something else that has become clear to me is that you also don't exactly know what you are getting into with the method you are following. It might be enough for the OP, but if you really would want to recreate that vase, creating the helical pattern and the ridges is the easy part!
The difficult part is how to blend these surfaces smoothly together.
I am 100% convinced that you are not aware of that.
As such creating a screencast and actually following your own advice to completely re-create the geometry is not just very educational for the OP but also very educational for you.
So while providing small sound-bit messages sometimes gets you a "like" or a "Solution" you are short-changing your own learning experience.
As to actually solving the "blend" problem I described earlier, I had created a screencast showing how to approach that geometry using T-Splines. While for some people who come from more traditional CAD techniques t-splines are highly suspicious, they completely solve the problem with blending between surfaces and if you stick with quad faces t-spines are inherently G2 curvature continuous.

What I can't understand yet is how an apparently nice and inoffensive curve can have that curvature comb.
This remembers me about some examples of Horizon Modeling in Fusion. They seem to be perfect at first sight, but Patch surfaces can have a strange curvature.
If you edit the sketch with the projected sketch, right-click on the projected curve, and select "break link" the projected curve becomes editable and it actually shows what it is comprised of.
It turns into a control point spline.
The best curvature on control point splines is achieved when all the control points are more or less equally spaced. However, you can see that in some areas they are spaced together much more closely. Those are also the areas where the curvature has these little spikes.
Depending on the design, this might not make much of a difference, but if a user gets used to using these techniques when higher quality surfaces are desired, this can lead to modeling problems.
