When to wear a scarf:

When you are driving your convertible with the top down on a Pacific Northwest February day,
Or standing around outside for an hour while your nephew plays in the snow.
When not to wear a scarf: walking! At least, that's how it is for me! I bundle up against the cold, but have a silent debate with myself whether to scarf or not to scarf. I'll look super cute with it on, but gosh darn my internal oven! I heat up so fast, the scarf is always overkill. Two blocks into my walk I know I'll be tossing my scarf aside and unzipping my coat halfway.
Still. It is a lovely, lovely scarf made by my talented sister. I look at it longingly when I head out to walk.
Nope. There is a time and a place for my scarf. And walking is definitely when not to wear it!
