Even the bottoms of the yoghurt bottles I used to make the planters got a productive life now. By putting two bottoms together with a magnet it can serve as a cool pin/clip holder and everything will stick to the magnets. Squeeze the most out of everything, be creative.
These mirrors are made from oven trays and a couple of pans I got from my girlfriend and my mother. Use them to cook your ego or to bounce positive energy around the house.
As simple as up-cycling gets. Turn an old oven tray into a magnet board instead of discarding it. I use the red one to put bulk spices in the kitchen.
