I don't have a linen closet, but it can't hurt to look, right? These are some that turned my head when I saw them. Just couldn't help it:

1 organizing tips from styleathome.com
2 from a house for sale in LA, via Recentering el Pueblo
3 This one's more of a linen cabinet. From Linens N' Things
4 No. Way. Is that a cedar-lined linen closet? I think I'm in love. From a how-to on refurbing an old cedar closet at Country Living.
