wagask uses a spacing to convey her point lot like in the word compressed where she moved all the letters together or in spaces where she stretches the space between letters out.

Goodman Uses a lot of outlines with different color fills in hi letters for example the products butto on his website. he also seems to love using big blocky letters like in his products probably to up the contrast as most of his work tends to be high contrast like his yellow and black wall art or even his black n white wall art

In contrast to the other two Edgerton creates/uses mostly novelty font link in her love lettering at the bottom of the page

one last thing i noticed about all of them is that almost none of them uses serif fonts if they can help it its almost all sans serif fonts that decorate their pages
