An index card on a white table. The information for the woad dye is handwritten in blue ink.
An index card on a white table. On the left is handwritten the continued woad notes in blue ink. On the right are 4 yarn samples stapled to the card. The BFL, BFL tweed, and mint yarns are off white slightly tinted light blue. The cotton yarn is a bright white.

Note: Late, I learned that laundresses used to use a little bit of woad or indigo on white linens and cottons to brighten whites.

Notes –

  • Fabric previously dyed with turmeric changed to pink, but back to yellow with washing.
  • Not enough pigment to overdye fabric.
  • Not enough pigment to overdye onion/avocado sugar cane or mullein bamboo.
  • Bare yarns hold some blue, but not saturated.
