I've had a few free samples of Shout Color Catcher sheets. It always amazes me how even old clothing leaks colors in to the washing machine water.
Did you know you can make your own laundry color catcher sheets?
You will need:
1 yard of scrap fabric
1 tablespoon of Washing soda
1 cup of hot water
Dissolve the washing soda in to your hot water. Stuff in your scrap fabric until it becomes saturated, then let it dry.
Cut off a piece (or precut the fabric and just grab a sheet) of your dried fabric and toss it in your laundry load. You're done!
