Grab your wrapper and your pile of coins. Make sure the wrapper is the right size—a penny wrapper on a quarter roll is like trying to squeeze a sumo wrestler into a toddler’s onesie. Not pretty.
Hold the wrapper in one hand, and with the other, start dropping coins in. Pro tip: slide them in gently, not like you’re feeding a slot machine after three cups of coffee. You want the stack to be neat, so each coin lies flat—if they’re crooked, the wrapper will fight you later.
When you’re about three-quarters full, give the roll a little tap on the table to settle the coins. It’s like burping a baby, but with less drool and more clinking satisfaction.
