I am trying to recreate the following shape in Adobe Illustrator:
But I am failing spectacularly. I can't seem to find the right distortion, despite having tried a bunch of different settings and effects.
I tried the envelope distort options, the effect distorts and warps. I tried the mesh distort, but the result was not good - the lines weren't connected even though I had created a normal grid, and I couldn't recreate the size properly.
