Your favorite jeans have faded from midnight blue to sky blue. You still love them, but not their new color. Or perhaps you're rethinking the purchase of that stone-washed pair. Re-dye your jeans yourself to restore them to their former dark glory. Fabric dyes are available at most drugstores and craft stores. You can devote an afternoon to the project and end up with "new" jeans to rock that night.
Fill a bucket with hot water and your dye, according to the instructions on the dye box.
Run your jeans under hot water.
Put on your rubber gloves. Put the jeans into the bucket full of dye. Stir them with a wooden spoon. For a light dye job, stir for 10 minutes; for a dark dye job, stir for up to 30 minutes.
Take the jeans out of the bucket and rinse them with warm water. Lower the water temperature as your rinse, until the water runs clear.
Wash the jeans in the washing machine with a mild detergent.
Let your jeans air dry.
