Just before hanging them, while they are still wet:
Grab each t-shirt from the top with both hands, then do a couple of violent whip-like movements. This has the same effect of stretching the fabric so that no ironing is needed.
"The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom."
(I agree that is a strangely satisfying thing. It does make hanging the wash up for drying slightly less tedious...)
Interesting, I never considered this a hack. Noone told me this, but I always do it. Ironing is never needed. I do it with pants too.
How does this contraption dry clothes? Looks like someone tried to take a clothesline indoors.
On a less sarcastic note: Water has no problem evaporating at room temperature. A batch of clothes is usually dry overnight. In fact you can even dry stuff at below-zero temperatures through sublimation.
After removing the laundry, we fold everything neatly, and leave them stacked on top of each other for 30-60 mins. Than we dry them with a standing dryer.
Haven't ironed t-shirts or jeans since we got married.
After removing the laundry, take your t-shirts and stretch them yourself, one by one, when they're still slightly wet. Grab them with two hands symmetrically, stretch horizontally, moving your hands down along the shirt. Do the same vertically, and with the sleeves.
Do not use a machine dryer, just a regular standing dryer like [1].
Put your t-shirts carefully, symmetrically on the dryer, and once dry, put them on a hanger. If you follow this, you will not have to iron them at all.
Source: been doing this for 4 years and I didn't touch the iron since. I have all t-shirts 100% cotton (though I buy only high-grammage ones) and they all seem brand new and ironed (the only exception being one particular brand whose collar looks bad unless ironed, I stopped buying that brand). YMMV of course.
