Here's a D-I-Y tip: instead of purchasing new cleaning rags and sponges when your old ones get too gross and torn up make some of your own cleaning rags from old pieces of fabric and clothing!
If you have a stack of clothes that you want to throw away then use those. Or when you are going through your clothes again and find those pieces of clothing that you know you will never wear again, (come on, let's be honest, there's plenty of that in all of our closets!) take out that clothing and start snipping it up!
No matter the clothing - be it shirts, dresses, skirts, jeans - you can easily turn something old and used up into something with a new purpose in life! You might even consider using old underwear - no one else is every going to use it!
I know it's a crazy idea, but really it's not. Instead of throwing things way, reuse them. It's good for everyone!
