|With much encouragement, I'm posting this actual non-sewing tip. But...like mentioned, this tip has the potential to leave you with much more room in your closet for the clothes you are sewing.
I recently read this tip on HGTV, so I can't take credit for it alone.
In your closet, turn all your clothes hangars backwards with the hook facing you. Then as you wear an item and rehang it, face the hangar back towards you as normal.
After a season, you'll be able to tell what you wear and what you might want to get rid of.
Simple, I know. But it works!
