Sumac tea draining into a bucket through an old window screen. Recipe calls for 10% sumac extract by weight of fabric, but since I have no clue to the tannin composition or percent tannins I was able to extract, just going to go for as little added water as possible to keep cotton wet overnight. Might put a brick on top and not n dilute. Still waiting for supplies before the next step, scouring cotton, then the tannin soak. #dyeing
