The link you dropped in the room that was your recipe, mentioned *soda ash* from a swimming pool supply store, it also mentioned *washing soda* like our grandmothers used... From experienced dyers telling me, the *washing soda* is not anywhere near as strong as the pool-supply store *soda ash* but close to the same thing, just a lot weaker... The recipe didnt say anything about baking soda that i could find....but whatever you used... SO glad that it worked !
