Cander, this is a little off the subject but I have to ask you a question since you own a ton of Diesels and are currently doing your Turbodenim experiment. I just bought the Koolter 8Y9 and I am wondering what the difference is between the Koolter and the tepphar(which you have, right?)? I really like skinnies so I hope I made the right choice. Also, do you have any advice with the Turbodenim? If I wash them will they no longer lose the indigo?
