Potholders must come in pairs

Right? I mean, who gives an odd number of potholders? So when I had enough yarn leftover from the dishcloths to crochet only three potholders, I looked for more yarn scraps to make a fourth that would have some of the same colors as the other three. It's obvious which one is the afterthought, but at least our friends will now have an even number of hot pads to use.
