Well I don't feel like the renegade after reading the posts from fellow non- prewashers........if I suspect a color will bleed, I will cut a small piece, put in cup of HOT water and see..if it bleeds..I replace it...easier that way, takes the possibility of yuck out of the project...also....using washing machine to do all this fabric washing,then dryer for drying..,then pressing...not energy conscious .....water/power....those with reactions to "new" fab, have no choice....
I just want to sew and do laundry another day!
