Here are some more dye samples I’ve made. The first is common bilberry (Vaccinium myrtillus) on cotton fabric and silk fabric. To get this dark purple color, it’s necessary to use common bilberry (Vaccinium myrtillus) with dark red flesh; blueberries (Vaccinium cyanococcus) with white flesh don’t work. The fabrics aren’t mordanted.
The second dye sample is an iron (iron liquor) and tannin (oak galls) dye on cotton fabric and silk fabric. It’s almost black on silk, getting a bit lighter with time.
The last is just iron liquor on cotton fabric
