I was (preemptively) packing away my knitted scarves today and came across my warm weather ones! They're so pretty, although completely non-functional for neck warming. Anyway, I can't wait to start wearing them!
>> If you keep all your wintery clothes in an old suitcase (like mittens, scarves, beanies... even fold up umbrellas), then it's easy to find everything when the season changes. I use the same bag for hats, sarongs and sunnies, then make the switch twice a year. It's not an exact science, but a reasonable way to keep organised I think.
