Cute idea I saw yesterday in a consignment shop.
They’d used pastel playing cards as earring cards!
They’d used pastel playing cards as earring cards.
They were simply in a rectangular box, but imagine how cute the idea would be clipped on a clothesline:
Pastel clothespins to display the carded earrings
I suspect the playing cards I saw were found at a dollar store, so keep an eye out. Imagine, that would be less than 2 cents per “earring” card!

Very cute idea. We use our business card to display earrings. Our cards laid out vertically with our colorful logo etc, but the flip side is a simple off-white w/our logo watermark, this is the side we use for displaying earrings. Whether the earrings are personal purchases or given as gifts, our contact information is easily accessible.
Sharon,
That idea is a “stealer”! : )
