Washing Jeans

I have a new pair of jeans that I'd like to last...
"To keep jeans from fading, wash in small loads in cold water (with more water than clothes) with all-purpose detergent. It's common for jean to shrink in length, so hold them by the waistband and legs and gently stretch them vertically before drying. Dry on low or medium heat; overdrying causes extra wear and tear, so take jeans out when the legs are done but the seams and the waistband are slightly damp."
