It’s true that there are better and better unbreakable outdoor dishes and drinkware available all the time. Long gone are the days of the standard ribbed paper plate or red Solo cup.
That said, who are you inviting to dine that requires so much dish-security? In my 30 years of entertaining indoors and on porch, patio, and lawn, I’ve never lost so much as a water glass, and I’ve had some lively parties. At one particularly memorable dinner, one of my guests decided to wear his napkin on his head. No explanation was given—or required—and all the glasses remained intact.
Instead of melamine, consider something special with an organic finish. Asiatica carries beautiful plates organically speckled like bird eggs. Their matte-porcelain fluted cups by Iyama Makiko, which resembles a flower in bloom, would be a perfect vessel for wine. Interested in a more generous pour? Their large glass goblets are elegant and sturdy and work well with water, too.
