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.
Pizza stone
Oh ya, those are great. If you really get into making homemade pizza, move to a pizza steel. A bit more expensive and a hell of a lot heavier, but better results.
I had one of those but didn’t get the best results and was unhappy with how hard it was to clean. However I got a baking steel a while later and that things been great. Really versatile
Heh, I got one of those from the dump! Best purchase I never made! I use it all the time, and it works rather well.
