Fill your bucket again with water and add half a bottle of bleach. Using your rubber gloves place your jeans into water. Depending on how light you want the tie dye parts to be, leave your jeans in the bucket for a few hours, checking constantly.
To get a mottled effect, you can use the old tie-dye method. Leave your fabric in the dye anywhere from 20 minutes to one hour. If it is still not dark enough, return it to the dye bath. Remember your fabric will be a lighter colour when dry. Use your hairdryer on a corner of your fabric to check it, and return it to the dye bath if it's not dark enough. To set your colour, add 1 teaspoon of alum to the dye bath. Leave the fabric sit for 5 minutes. It is always best to do test swatches when doing your own dyeing.
