It's a lovely vintage hankie case - made from, I think, fine linen. I don't know if you can tell from the photo (click to embiggen it) but the flowers and the green leaves are appliqued and then additional stitching has been added. The blue area has been satin-stitched. The green edging is hand stitched onto the case.
Here it is open - and inside were a number of lovely hankies, including the pretty one with the red crocheted edging.
This belonged to my friends mother and she decided I would treasure it more than she would. She was right! Thank you Jan!!!!
