What's that, you say? That's when I make one earring just slightly different than the first. It isn't different enough to make anyone say, "Hey look! How cute! These earrings don't match, but they sure are fun."
Nope, mine was of the, "Something is wrong with these earrings, but I don't know exactly what it is," variety. And it took me awhile to figure it out! But figure it out I did, and I immediately made one more earring in each variation.
