Well, let me tell you about this afghan.
My husband's grandmother made it when she was in the early stages of dementia. As part of her dementia, she had a compulsion to do the same "helpful" things over and over and over. And she really wanted to help, to be useful. Like, she made a huge pile of all-the same cloth items for her church altar ,always convinced that there was a great need that she could barely keep up with from day to day. It was an item where only a half dozen or so were needed, but she could not stop making them. This afghan was made during a period when she had been steered away from that activity, but she was similarly frantic and compulsive about making afghans.
The family kept her supplied with yarn and she made afghan after afghan. She had lost judgment about when to stop. That meant two things 1) She turned out dozens of afghans, and 2) she did not know when to stop a "row" (if that is what you call it with crochet. So this afghan is more than twice as long as is needed to cover a bed. We use it doubled over, lengthwise. It also is very wide, so it hangs down the sides of the bed. The thing is monstrously big.
The afghan has many colors, but also different types of yarn. It has acrylic
and wool, both! I have machine washed it before and have to pull and reshape where the wool is, or else the whole thing becomes weirdly ruffled.
The bath tub washing went well, though it was a huge effort. I got in the tub with it barefooted and did the grape-stomp dance on it.
I kept it draining there overnight and will carry it to the washer today to spin it out some. Then I think I can line dry it in the basement.
