T.S.
LOL these responses are funny. My kids were a LOT more careful and aware as toddlers than they are as teenagers. The only time I ever used plastic or paper past the age of two was outside, on the patio (concrete.)
And for what it's worth, I find adults more destructive than children, especially if alcohol is being served.
I love mason jars, especially if the party is on the grass, what's the danger/harm, really?
