What is something really stupid you purchased that turned out far better than expected?
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.
I bought a milk frother recently. I don’t even drink coffee. But I saw that it was a great way to make a protein shake without clumps and easy to clean. It does do that. But it also been great for mixing my pre workout or soap for cleaning. I love it!
