I sort of enjoy the washing and prepping process. It is kind of like a special ritual! When I can afford fabric, especially nice QS fabric, it is such a treat, I guess I like handling it as much as possible...
I also wash out of necessity. Like so many on this board, I need to get rid of the "junk" on the fabric with "Free" type detergent and lots of rinses. Any chemical I can get rid of seems to ease my itchy skin, stuffy sinuses, and arthritic hands.
