What you need is:
- a t-shirt or a top
- some cardboard that you can fold
- black paint or any colour paint you'd like your inkblot to be in
Take your cardboard and put it inside the shirt, put paint on the shirt and fold cardboard - tadaa you've got an inkblot. Kinda like when you were a kid and you played around with paint on paper folding it with new colours. Basically the same idea here, just more mental and old.

Idea for this I got from this DIY video on Youtube:
