I believe we all do our own thing and that is the way it should be. I did make a few things with out pre-washing and this bow tie wall hanging I used in my office is the main reason for my washing rule for myself. I also would not like fabrics pre-wased except we also starch and iron them and they are as crisp for working with as if they had never been touched. For those of you pre-washers who are doing a lot of fabrics try using a garden sprayer to dispense the starch mixture. We use Sta-Flo 50-50. Starch/roll/put in plastic bag and freeze till we are ready for ironing.
My husband will never let me forget the time I was ironing brights and in the collection of bags I brought from the freezer was a bag of brocolli.
