I don't know about you, but I don't know that "whiskers" on my jeans are that important.
Yahoo Style recently declared jeans should not be washed, but frozen (right alongside your food, mind you!!!), and simply spritzed with vodka if any dirty spots or smells remain. To wash jeans ruins the intended natural fading of lines radiating from the crotch, they claim. I kid you not! Read the linked story above if you don't believe me!!!
I've been washing jeans, not just mine, but for the whole family in every family I've been a member of, for pushing nearly half a century now. I recycle the denim every chance I get when knees, saddles, seams or pockets wear thin. I get many, many miles out of the recycled denim, as well, and I'm washing it just like I wash the jeans. Soap and water. Washing machine and dryer. Shrink them babies. Fade 'em, too. Soften the cotton.
My husband's grandfathers and uncles worked on their farms, and they wore jeans. I guarantee you they did not put their jeans in any ice box. And jeans would not have been worn dirty week after week after week. No children and grandchildren would have resulted if those cowboys had displayed such fashion sense. Wives would have abandoned those stinky cowboys lickety split.
Denim whiskers, indeed!
