This question already has an answer here:

So here's the thing. I'm trying to make a sailshade. I'm going to be making many of these over time, so I want to find a fast and accurate way of doing this. Basically, a sailshade is normally 3 or so fixed points with a curve between the fixed points.Sailshades

That's how most of them look, although some are more complex.

What i'm trying to do is make a plane that i can shape and stretch to how it needs to be, that way i don't have to constantly modify all the vertices. Sadly, i'm not an expert at Blender yet, and was wondering if there was some way to 'control' the curves that i put on the plane? For example, i could have a square plane with 8 'control points'. 1 on each point (4) and 1 between each point (4) to control the curves.

I'm pretty sure his is possible... but I haven't quite figured it out yet... Anyone able to help?

Please and thank you!

That isn't exactly the solution i was looking for, using a cloth modifier doesn't really work for what i'm doing.

In addition to Duarte's answer, I'll add another method. It will use the subdivision surface modifier as well, but another method to create the sharp corners

  1. Add a plane. Subdivide it once. Add a solidify, bevel and subdivision surface modifier.
    enter image description here
  2. Since the sail would have a thickness anyway, the bevel modifier comes in handy. Otherwise just scale the value down untill it is no longer noticeable (but no 0). Use a high number of segments and a high angle. The angle has to separate the corners from the sides. The corner angles are going to be > 90 in your example, so I entered 80°.
    enter image description here
  3. You can now easily edit the shapes. Other shapes (not just quads) are equally possible as long as there is a distinction between side angle and corner angle.
    enter image description here

You could also use NURBS surfaces. Add a surface, delete the standard additional points and close the endpoints, by checking Endpoint U and V.
