Most of the time, I test the fabric. Learn this trick from Harriet Hargrave. Wash it in hot water along with tiny amount of your normal laundry soap and put it in a small container and shake it on and off for at least 5 minutes. I then rinse it and put it on a white paper towel. if it doesn't bleed, I don't worry. If it bleeds I will wash the fabric. I use color catchers in every load of laundry I do. Best invention since sliced bread !!
