chatalaine

I found this item at camberwell market on Sunday and thought to make a chatelaine  I love the inside of it - the text that tells of its origins as gift and the perpetual calendar missing the piece that makes it work.

what will make it a chatelaine?
what does the person who wears this skirt keep with her as important and needful?

*paper and a little pen
*an image
* a device of some obscure function
