Step 1: hold up by a short edge, fold vertically. (In half or thirds, your choice.) Step 2:tuck short edge under chin, reach down and grab edges at hip level. (For my body that's dead center of the towel length, but I'm short. You might have to grab waist-high. Check in a mirror and from then on you can do it by feel.) Step 3: Let go with chin and raise center, creating a folded edge. Step 4: reach out over a surface, touch down the unfolded edges and lower the folded edge towards you until it's halfway, then push the folded edge away and lower it atop the other edge.
Why do that at all instead of just... you know, folding it in half? Bonus points, if you're tall and have the wingspan to literally just hold it open longways.
I have several towels to fold and put away each time so they at least have to be folded in half lengthwise and twice the other way to make a nice square stack. And I'm 5'1", having lost an inch from my younger height. I only use one towel a week myself but it's not just me. Now, washcloths I do only fold in half. I used to do fourths, but it made two stacks, that took up the same space as one stack of single folds.
It only takes me a few minutes to fold and put away two large loads of laundry, even when the cat helps. It's one of the few household chores that's actually satisfying instead of drudgery.
I'm also good at folding fitted sheets into a nice tidy unwrinkled square despite the fact a queen sheet is well beyond my wingspan.
Yes, unlike your old bedroom which is the same size, your mom has very likely shrunk a little from when you were a little kid. We lose bone, and we've carried a lot.
Yeah, I think your height is the main reason to choose this convoluted (but functional) method. I'm not even tall by modern standards, only 6ft (183cm), but that's still enough to fold a queen size bed sheet in quarters without having to hold it at a third point
I grab two corners along the long edge and pinch with one hand, and slide my other hand along the length until it's tight in the middle, then I just meet that to the corners in my other hand, then turn it to the side and fold in half
Can't relate cause I've gone out of my way to avoid seeing that video. Somehow I've managed to avoid seeing it for the 17 years it's been around — literally half a lifetime ago for me — yet I haven't even seen a screenshot (oh god I'm getting old).
