The most rewarding dyes for me are from the plants that I can harvest myself. I am always most fond of the oranges. Here are a few recently dyed hand spun alpaca skeins. (For sale in my Etsy shop!)
LtoR: marigold (tagetes)/tin mordant, madder root (rubia tinctoria)/tin mordant, sunflower (helianthus annus)/alum mordant.
