fans

Not the sort who send you e-mail or ask for autographs; the sort you hold in your hand, for cooling yourself.

Does anyone have a recommendation for how to hang folding fans on a wall in a manner that won't damage them? The one time I've done it, I've put in two small nails just inside the outermost sticks, below the fabric, but that warped the fabric where the weight was resting on the nails. I'm looking for a better solution. (All I can think of is nails on either side of the pivot pin, but they'd have to stick out awfully far, and I'd still probably need small nails at the top corners to keep it open and flat against the wall.)
