When unsanforized denim comes into contact with water, it shrinks while drying. So, we need to get these puppies wet. Plug your bath tub and turn the hot water all the way on (obviously be careful, it’s hot). We only need enough water to submerge the jeans all the way. Once you get to that point, turn your jeans inside out to protect as much of the indigo dye as possible, and place your jeans in the water, making sure they get completely wet.
