How many times do you have to put shirts in the dryer to shrink them?
There seems to be an unwritten law about shrinking: The amount is inversely proportional to the desire for it to happen.I have several shirts that, purchased oversize, are unwearable due to non-shrinking. On the other hand, some of of my favorite shirts now adorn teddy-bears because I liked 'em so much.
If you use mine, just once! Lol seriously, the hotter the setting which is usually for whites/cotton, dry for an hour, then when cooled, run again for another half hour. That should do it!
Is it cotton
Make sure to wash in hot water first.
