I don't really know what this is called so I thought I'd ask here. I'm trying to make this kind of line effect inside a shape, and don't really know where to look or what to do to learn how to do it. Any help is appreciated!
The shape (it's not text)
the effect I want to fill the shape with.
The simplest solution is turning your target shape into a clipping mask.
You could create a horizontal pattern, fill the shape with it and rotate the pattern fill.
Hey, this is great thank you! What font did you use for the T?
Thanks, I just picked a random font, in this case Avenir Black.
