Not really my kind of 'design' but I quite like that nonetheless! It's very interesting and original. The tree one would be me pick if I had to pick one.

May I ask how you do that? Is it just painted on the fabric?

Yup, just bleach direct to any fabric
Thx a lot. And, once again, real nice job :)
Nice, is the bleach thickened to prevent bleeding?
Sometimes yes and otherwise no haha
I’ve been doing something I assume it’s similar. I put a piece of cardboard or wood inside the shirt, clamp it with something to make it easier to draw without the shirt moving around. I pour some bleach in a shot glass and use a paintbrush. When you’re done soak the bleached area with peroxide to stop it from continuing to react. Experiment on some expandable material first. Also I use some chalk to roughly get an idea of are and scale I’m drawing.
Thx for explanation :)
