You don’t throw a shirt down on the ironing board all wadded up and just press your hot iron overtop it.
I mean, maybe you do, if your intention is to make some kind of shirt sandwich and pressing the wrinkles deeper into the fabric locks in the flavor or whatever.
But usually, you lay the shirt flat. You make sure the collar isn’t folded up, and you smooth down the sleeves. Then you get to ironing. Giving yourself that minute to prepare the canvas, so to speak, makes the work easier and promises you a better outcome.
It’s the same with writing.
