I finished one pronouns T-shirt; I've also made a black version with less overlap between each line, but it's currently in the wash to get the chalk lines out.
I used Pebeo Setacolor fabric paints and a cheap alphabet stencil - not sure what the font is but it's similar to Impact, I guess?
The lettering is a bit rougher than I'd line. The Pebeo paints are a bit too liquid to work easily with a sponge stippling brush, but using a regular bristle brush with a stencil can be a bit of a challenge too. I think if I make any more, I'll make my own text stencil first so I don't get as many issues from having to reposition the stencil for each letter.
(Unfortunately, not enough space across the front to do they/them/theirs instead, at least on the size and style I wear.)
