These are shirts I sewed and dyed on one sunny afternoon some years ago.
The open collared shirt was folded into a small triangle shape first, then it was dyed with two pieces of triangle-shaped wood sandwiching the shied and tied with a string around the whole thing to secure the bundle. It produced an interesting patterns, and I liked it!
The sleeveless pull over shirt was dyed without any tying. However, it still had nice random patterns.
I should have tried some more dyeing this summer! Now it feels a little too cold to be working with water outside.
