My grandmother handed these down to me… they’re a combination of coffee cup and cookie plate, with an indentation that makes it easy and pleasant to hold in one hand. (There is a little rim under the coffee cup, to hold it in place, just like a saucer has).
You know that problem you have, when you want to circulate, and you want to have your coffee? Problem solved.
Clever and pretty = good design.
* If I can find good design on a regular basis, this will be a regular blog post.
