Your Wardrobe
You can recycle parts of your wardrobe to become part of a new wardrobe. An old tshirt can be recycled to be a headband or a belt.
If you have jeans that still fit but the denim on the legs is too worn turn them into shorts.
Do you have a jacket and the sleeves are worn? If you remove the sleeves you can wear it as a vest.
Those clothes that are too worn for everyday use can be used for a yardwork or cleaning wardrobe.
