For my daughter, I found a good way to bring her hankies on her clothes those have no pockets.
I put a ring on her clothes, and she can put a hankie on it. I also made a small pouch with a clip. She uses it when she goes outside with her friends, put some candies in it.
The ring is for knitting.
She can use it without refold, just wipes her hands.
I also use them hanging from my bags.
Because my son needs hankies often, it's convenient.
The one with face is for boys. Maybe they don't like ribbons so much.
You close them with snaps on the belt.
They are convenient and cute, aren't they?
