Hello guys - Illustrator related question

[Egg Bramhill]

Welcome to TG MFR.

I think HandDrawn is correct:

... as I read it, the OP's attached PDF is what they wish to achieve, not what they have done...
I can only say, that which works for large fonts will work for any font...

It's interesting image though as I attach part of the original image. What makes it more than just a font with a vertical linear fill (as in my image 1) is that it has subtle variations on the fill on different characters of the text. I created this by cutting the text up and applying various circular and elliptical fills (as in 2).

3 is just the same 9 shapes that make up the text exploded.
