I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
An oversized poncho cape from the local Goodwill. It was woven in different shades of blue and while I’d never wear it outside, I’ve used it as a wearable blanket at home for a few years now.
I found out it was actually hand made, and costs 300+ USD from the original shop. Bonus points, I feel like a wizard when I wear it
