Rit Dye Liquid 8 Ounces-Tangerine

good for nylon, bad for cotton, very bad for tie-dyeing:
All-purpose liquid dye contains a mixture of an acid dye, which works on nylon, silk, and wool, but not on cotton, and a direct dye, which works rather poorly on cotton. If you are dyeing cotton, you will be much happier with fiber reactive dye, because it is easier to use (no boiling water!), brighter and prettier in color, and much longer lasting in the laundry. Fiber reactive dyes sold by Amazon include Dylon Cold Water Dye, Dylon Permanent Fabric Dye, and, best of all, Jacquard Procion dye. Do a search on Amazon for those dyes now! If you do choose to use all-purpose liquid dye, first, be sure to buy enough. Each bottle will dye only one pound of fabric for a medium shade, or one-quarter to one-half of a pound of fabric for black; for a pastel shade, you can dye two pounds of fabric with one bottle. When dyeing nylon, silk, or wool, add six tablespoons of white vinegar per gallon of water; for cotton, do not use vinegar, which won't help, but do add one cup of salt. Using a cooking pot which you will never again use for food (Rit dye is not safe for utensils used in food preparation!), bring the dyebath to a good simmer, 190 to 200°F, add your garment, and continue to simmer for half an hour, stirring frequently. For solid colors, be sure to use a pot that is large enough to allow the garment to move freely. Even when all-purpose dye is applied to cotton correctly, with simmering hot water, it still tends to wash out in the laundry and bleed on other clothing. To prevent both of these problems, you must apply a commercial dye fixative, such as Retayne or Raycafix. Try a web search to find a place from which to order it. Washfastness of items dyed with all-purpose dye is greatly improved by the use of the right fixative. Vinegar and salt will not make all-purpose dye on cotton last long in the laundry.

First attempt at dying VERY faded jeans went exceptionally well:
Never dyed anything before so I don't know what I'm talking about, but I thought it would be fun to try. I just ran hot water front the bath tub into a 5 gal. bucket - filled it a little over half full. Dumped the whole bottle of dye and a cup of salt into the bucket and stirred it with a dead branch i found in the yard (seriously). The instructions said to stir constantly, but that sounded not fun, so I just stirred it 4 or five times over the course of an hour being very careful that no dye splashed out into the tub. Carefully drained the dye and hand rinsed the jeans under the tub faucet until the water ran clear (took quite a while) then cleaned the bucket and tub and hand washed 'em again with a little detergent in the bucket then dried them inside out. I gotta say, maybe it was just beginner's luck, but they look awesome! They're now a deep dark shade of blue. Couldn't be happier. Only thing I'm gonna do differently next time is get some rubber gloves and safety goggles.

Excellent:
On my eco-quest to save old designer leather purses, I mixed this dye with the brown liquid dye and got a wonderful warm brown that was perfect for the cross body 80's swingback Coach I restored. The purse was originally cream and the pebbled leather took the dye beautifully. I don't use as directed. I have a dye bucket. I boil water, add some salt, add the dye and put the bag in the bucket. I cover and flip it occasionally for the following 24 hours. I then dump out the dye and wash the item to remove the extra dye and air dry. Works like a charm.
