Testing vegetable dyeing

kasvivärit

For my next projects I need vegetable dyed yarn. Here are results from dyeing tests done this autumn. Reds are dyed with madder. Darkest one has also indigo over madder. Green colors come from variety of green plants. Blue is from indigo. Bright orange-yellow got their color from onion skins. Brownish yellow color is from lichen.
Indigo dyeing was tricky. My first indigo bath was slightly too alkaline and hot. It worked like hair remover products: loop of yarn become like weak rubber band.
