Solar dyeing wool involves using the sun's energy to naturally infuse color into the fibers. Here's a straightforward method:
-
Prepare Your Materials: You'll need a clean glass jar (the size depends on the amount of wool you're dyeing), wool yarn, your chosen dye stuff (e.g., turmeric, blackberries, onion skins), water, and a lid for the jar.
-
Choose Your Dye Stuff:
- Turmeric: Use approximately 2 tablespoons of turmeric powder per liter of water. Turmeric yields a bright yellow color.
- Blackberries: Use as many blackberries as you can fit in the jar while still allowing room for the yarn. Blackberries produce shades of purple or lavender.
- Other options include onion skins (yellow/orange), marigolds (yellow), and avocado pits (pink).
-
Combine Dye Stuff and Water: Add your chosen dye stuff to the glass jar. Then, fill the jar with water.
-
Add Yarn and Stir: Gently submerge the wool yarn in the dye bath, ensuring it's fully saturated. Stir well to distribute the dye evenly.
-
Secure the Lid: Put the lid on the jar. This helps prevent evaporation and contamination.
-
Solarize the Dye: Place the jar on a sunny windowsill or in another sunny location.
-
Mix Daily: At least once a day, upend or gently agitate the jar to ensure the dye is evenly distributed and penetrates the wool fibers.
-
Wait and Observe: Allow the jar to sit in the sun for at least two weeks. The longer it sits, the more intense the color will become. Monitor the color of the yarn regularly.
-
Rinse and Dry: Once you're satisfied with the color, carefully remove the yarn from the jar. Rinse it thoroughly with cool water until the water runs clear.
-
Dry the Yarn: Gently squeeze out excess water and hang the yarn to dry in a shaded area, avoiding direct sunlight which can fade the color.
Tips for Success:
- Mordanting: For more colorfast results, consider mordanting the wool before dyeing. Mordanting involves treating the wool with a substance like alum to help the dye bind to the fibers. However, for solar dyeing, this is sometimes skipped for simplicity.
- Jar Size: Choose a jar that's large enough to accommodate the yarn and dye bath without overcrowding.
- Sunlight: The more sunlight the jar receives, the more effective the dyeing process will be.
- Natural Dyes: Remember that natural dyes may fade over time, especially with washing.
- Safety: Wear gloves when handling dye materials, especially if you have sensitive skin.
