You put your wash into a basket, carry it to the lines and pin the wet wash on with wooden clothes clips that have metal spring-affairs. I'll have to get into clothes pins at another time. Sheets don't matter much but when you get to the shirts you pin them by the tails, not the shoulders because that would cause pin marks on the shirt and they're hard to get out when you iron. As to the washing itself, most of us have washing machines now but we remember when we didn't and had to wash in big old tubs. Blueing, bleach, lye soap, wringer washers and scrub boards are things of the past.
Some mature ladies do still keep blueing for their hair.
That's another thing I'll explain at a later time. Aprons are handy on wash day because they have pockets to put the clothes pins in. Wash day is a good neighboring day with visiting, talking back and forth, trading wash tips over the back fence. I gave you a few weeks ago. There are a few commandments such as never put the wash out on Sunday.
