Add 1/2 a bottle dye to 3 gal. HOT water for each lb. dry fabric. Add wet fabric, and stir CONSTANTLY 30-60 min. Rinse until water is clear. Wash in warm water and detergent. Clean up with bleach.
Reality: add almost the whole bottle to a bunch of hot water in a bucket. add wet fabric and stir for a minute. listen to ill music and completely forget about dyeing. remember after a while and stir for another minute. rinse for-fuckin-ever until you realize that this totally sucks and that next time you should just get a pair of new, black jeans instead. clean up with shower gel.
