Dying T-shirts for vibrant color
Am wanting to dye some white all-cotton t-shirts. I've tried this previously, but when the shirts are washed and dried, the colors end up being pale pastels. (I've used Rit & similar brands of dye.) I would like to find out how to create vibrant colors that last. I don't care if I need to soak in dye for a month. I just want rich colors.
