Useful tip: Doing your laundry, a dye bath, and oxidizing a silver chain with hard boiled eggs - ALL at the same time - can be a little much, and will fog up all the windows in your kitchen. Consider planning these tasks for separate times, unlike yours truly.
Last week I started a couple of projects dying fabric with natural pigments. It takes a few baths to do this (scour, mordant, dye). Here's the first batch I started in my kitchen! Mordanting (left) makes the dye adhere to the fibers. After I finished that step, I used a logwood gray pigment (below) to dye the fabric.
