Few wooden items have been excavated in the past few decades, here's a photo of a some bowls and spoons which were found
It's tricky to find something that resembles these items but if you go to fleamarkets and yardsales you should be able to come up with a few nice looking ones, like you see hereunder.
These items make great camp decoration to give it all an authentic look. You'll never be able to create perfect authenticity, but this beats plastic! The spoons you see are made of horn.
