The time is usually an estimate, or the best case scenario in my head. If I have to stop and add more time, I do. But 10 hours is probably what google maps told me it is. I drove straight 9 hours or so once, I think I stopped twice to use the bathroom/get a snack. Got there at 2am. It was rough, wouldn't do it again.

Hello, I am the tumble dry spouse and the number of times I've been thwapped in the face with elastic in the middle of the night is too damn high. I'm going to get some of these. Do you have a tutorial or explanation of how you sewed some?
