Dyeing clothes
How is this done properly?
My work uniform is black (t-shirts, sweatshirt, shorts, trousers) and they are very basic quality and fade very quickly. They turn a 'pale black', almost grey when washed over and over again.
What do I need if I want to dye my work clothes so they remain black? Do I get one of those round tablet things and add it to water? How much of it and will the dye come off onto my skin and make a mess of the kitchen sink?
I want to try this out but need advice first. I don't want to ask my wife because I know she wouldn't want me to do it, so I would wait until she goes out and then dye my clothes when she's not watching.
Any advice with this? Thanks
