went on a trip to Taipei. not one bag, brought multiple bags because I planned to buy a lot of food to bring back to family. Taipei in July is very hot and humid, had to change my shirt around mid afternoon. i havent tried the towel drying method yet, figured it was a great time to test it. hand washed the 2 shirts I used, then rolled them up one by one. by the time i hung them up, they were no longer dripping. after ~8 hrs, they were completely dry and wrinkle-free. steps I took:

1. skipped the stepping on the towel part. instead, i wrung the shirt to remove excess water.
2. rolled the shirt-towel into a burrito and made sure that the roll is very tight then wrung it again.
3. flipped the towel and also flipped the shirt. made sure that the opposite side of the shirt now makes contact with the fresh side of the towel.
4. repeat the rolling and wringing.
5. flicked each shirt with a strong wrist movement (snapped to reduce wrinkles).
6. hung them on the backs of plastic chairs.

these were ordinary cotton shirts (Hanes, to be specific), i did not use travel shirts with specialized blends.
