Making Denim Blue

Hello,
Can I still buy denim bluing for my blue jeans? Can you tell me where to get it? What is your opinion on bluing?
Thank you,
Holli

Holli,
Bluing is a laundry product for making fabric whiter or brighter. It’s not a dye. In the old days white cottons had a tendency to turn yellow, and bluing would whiten by making the yellow move the opposite way on the color wheel.
The Rit website has some interesting info on over dyeing or re-dyeing denim. Check it out at www.ritdye.com. Another alternative is to over dye it with one of the industrial dyes available at www.dharmatrading.com. These are hands down the easiest dyes to use – throw the packet in a load with hot water and agitate for 20 minutes. Run a rinse load, that’s it.
Let me know if you have more specific questions.
