Starting with the birth of my son, the never ending need to have the washing machine running with the laundry loads that comes with a baby, I was doing laundry all day; fearfully separating whites, lights, dark, etc. I made the mistake of mixing lights & darks in the wash after a expensive shipment of baby clothes arrived, only to find the colors has faded and the lights had been smeared. If you have kids or not, I recommend using these in all your loads, they actually work, I could not believe my eyes the first time I used one and it came out all brown while the clothing looked newer. I use these on my clothes now too as they do really well at catching dyes from all kinds of pants and jeans, also a must have for the first wash before wear of any new clothing article as these papers will catch the dyes & the clothing comes out looking new and not the dreadful faded color. They are hard to find in stores and I finding them here on Amazon with the option to "subscribe & save" which I do, is a great way to save money and a great way to always have them instock for your home.
