In this post I indicated that I would probably be dotting on plastic eggs too.
And that's what happened today.
The eggs consist of two halves, which made doting easier. (With a whole egg, you can only dote half, then let it dry and then the other side.)
This is my result. On the red I only dot with white.
And on the yellow used various colors.
Both I deliberately did not (too) full.
So there are infinite possibilities.
You could also change equal halves, for a playful effect.
