Use vinegar to keep color from fading
Everyone hates it when they buy a cool black t-shirt or black jeans and a couple month later they are starting to fade. Here is a way to reduce the chances of that. When you wash them for the first time, put just a 1/4 cup of vinegar in the wash machine and run the washer. The vinegar locks the color into the fabric in much the same way it does Easter eggs.
