The process we use to hand dye our sweaters varies depending on the color of the sweater:
For our Blush sweaters, we use steeped black tea for the dye bath.
For our Crimson sweaters, we use beet juice for the dye bath.
For our Indigo sweaters, we use a mix of blueberry & blackberry juices.
To prevent color fading, we also use what is called a mordant, to fix the dye.
