Drilling

If you're going to purchase those pretty zinc pots in Monprix with the lacy edges and you'd like to use them as flower pots outside rather than cache pots inside, you'll have to drill a hole in the bottom to save the roots of your plant becoming waterlogged and rotting.  Don't turn the pot upside down and press too hard on the bottom to drill as you'll bend the lacy edges.  Instead, try to turn the pot on its side and drill sideways.  You might need someone to hold the pot still as you might have to press quite hard and the drill bit will suddenly pop through when you've made your hole, so mind your fingers:-)
