primitive antique fluted tart tins, mini cake baking pans for upcycle crafts display

Collection of seventeen lovely rusty crusty old metal tart pans, rounds and ovals. Most of these are about 3" to 3 1/2" across. I think they probably are a little rough for bakeware, but they'd be wonderful pieces to upcycle (ornaments? wind chimes? a wreath?) or display as the are.
