I have dyed white fabric with tea. Wet your fabric first. I used about 12 bags in a quart of water and steeped it about 15 min. then added it the smallest load in my washer with the hottest water . Then add wet fabric , agitate about 5 mins. then I let it set about 30 mins. agitating twice. Then allow it to finish its cycle. Check for uniform color, then dry.
