These cottons are dyed with blackberries from my freezer. The bottom one has a mordant of white vinegar. I love this colour! The middle one has no mordant and is more crushed strawberry. The top one is blackberry and turmeric which is a pretty gold/pale lilac. The colour's more obvious than the photo in real life.
I want to find a blue I like now and I've seen a lovely effect using black beans with a soy milk mordant? Anyone tried that, or have any tips or combinations which have worked well?
