Double the fun today!
I had heard this tip a long time ago but stumbled again recently on The Ol’ Switcheroo:
On January 1 (or thereabouts), turn all the hangers in your closet backwards. As you wear an item, hang it back up the right way. In six months, any clothes that are still hanging backwards are really good candidates for donation.
If you’re short on closet space, use luggage to store off season clothes. Unless, of course, you’re a flight attendant or pilot.
