Let's be honest; home decor can be expensive. And by the time you've spent your life savings on a couch, a bed, and other large home necessities, there's not a lot of room in the budget to buy a $300 lamp that's just going to sit in the corner of the room. That's probably why this person decided to craft their own lamp from things lying around the house, including plastic cups, pie tins, and a plastic cow!
They probably could have opted for more generic everyday items like shells or an old wine bottle, but there are no rules in the DIY craft world. And even if there were rules, this cow lamp probably would have broken all of them.
