While most people don't encounter any issues with briefcase-style picnic baskets that are turned on their sides while carrying, it's easy to understand how this design could generate a bit of anxiety. At the end of the day, there's no right or wrong way to pack a picnic basket, but using a bit of common sense doesn't hurt, either. To keep contents from getting squashed, pack heavier items like fruit, cheese, or jars at the back and softer foods like sandwiches or cakes in the front.
