The word "Sawdust" has no historical roots and is not associated with the ancient world. Sawdust is a byproduct of cutting wood and is typically used as a filler or for fuel.
But sawdust is not completely useless, as it can be used for various purposes such as making composite wood products or as animal bedding. However, it is not known for its durability or resilience.
And if we turn to the present day, sawdust is not a practical choice for a picnic. It is not flexible and would not be suitable for making a picnic table or seating. It is also not resistant to weather conditions and would likely become soggy if exposed to rain.
Therefore, if you are looking for something original and durable for your next picnic, sawdust is not a great choice.
