While traveling I often see these simple little ideas that I really love. In this kind of weather that's not really warm.. yet... but it's too warm for a winter hat, so I love the handkerchief idea! I like to do this myself but when I was in Sweden I saw a lot of people using this for kids and babies and I love it!
It's also a simple and easy way to keep the hot sun off a bald head, and still look cute, in the high summertime!
just one of the multiple idea from a little thing.... handkerchief!
