Sladic via Getty Images Ironing a shirt is one of those things ― like perfectly cooking rice , or doing a push-up ― that sounds easy but can be surprisingly hard to perfect. Personally, I always end up pressing a concertina-like line midway across the back of the shirt whenever I move it across the board. I’ve tried everything; it never doesn’t happen.

They recently revealed a secret function of some irons ― and it’s proof the gap between some irons’ plates and the rest of their body doesn’t have to remain decorative. What’s the secret? In their video , they ran the tip and edge of a shirt collar between the iron’s hot plate and its body.

It had a similar effect to using a straightener on the area, which some Redditors have sworn by for years. Advertisement Though the iron’s groove doesn’t cover the entire width of the collar, it does a beautiful job of giving the tip of the fabric a sharp, crisp, almost starched look. And @rawdenimenthusiast revealed on his Instagram page that the hack doesn’t just extend to regular shirt collars ― you can use it on T-shirt necks, too.

“Say goodbye to wrinkled collars,” he wrote , scooping the iron’s gap along his T-shirt’s topmost section. View this post on Instagram A post shared by RawDenimEnthusiast (@rawdenimenthusiast) People were fans of the trick Though we couldn’t find any evid.
