How do I repurpose old hankies?

I've seen them used on pictures from vintage patterns to act as the skirt, I've seen them framed, & used as curtains or a valance. Here's a link with more ideas:

Shadow box or have a piece of glass cut for a table top (dresser, coffee table, etc) and put there. I did that with a doily my MIL made on a night stand.

Pillows. Add to a pillow front. Some people make baby toys out of them with a pattern for a small stuffed animal. Hang a lacy one off of a shelf halfway over the lip of the shelf and use books or vase to hold in place. Make a great valance above a window with ones of similar color by folding one corner over a curtain rod and keep adding until you have enough to fill the window width in a bathroom or bedroom.

Lots to see here, I especially love the idea on the top left:

I have seen them used as a valance over a window but they may be too delicate for that. Could you try hanging a few in picture frames to make a collection or art out of them?

Hello. I’ve seen vintage hankies used as curtains and shower curtain with liner.

How about shadowboxing? That's what I did with mine. Some are from the late 1800's to the late 50's. Then hung in my hallway so they did not get sun damaged. Here are some options!

I framed a square scarf and it was so pretty!

I have several antique items like you, given to me by my late grandmother. I have placed them in glass protected picture frames with colorful backings. And I have placed them between round glass tabletops. Then placed the tabletops on an antique wooden stool and made a bedside table.

You could frame them? My friend has her Grandma's framed and they are lovely.
