My understanding is that once you use the Retayne to fix or set the colors, the final owner of the quilt can wash normally. Perhaps someone else can chime in here to correct me if I'm wrong?
I'm asking how to get the water up to 140 degrees as I have a batik quilt with purple and aqua and I forgot to wash both fabrics before quilting, so I want to use Retayne to set the colors, so my quilt and all my hard work won't be ruined! Plus its a wedding gift for my niece....ack! I can't believe I forgot to wash the fabrics!
