How to Dye Yarn with Black-Eyed Susans

Materials & tools you'll need

Step 1 — Gather your materials and permission

Before collecting anything, get permission from the property owner to pick black-eyed susan flowers — many of the best patches grow wild at the edges of forests and fields. Once you have the go-ahead, gather a large basket of fresh, vibrant flowers. You'll also want a large pot suitable for holding both the flowers and plenty of water, clean rainwater or tap water to cover them, and the yarn you'd like to dye.

Step 2 — Set up a clean workspace

Before you start the dye process, make sure your dye pot and all the utensils you'll be using are thoroughly washed and free of any residue that could contaminate the dye bath or affect your finished color. Lay out any additional supplies you'll want on hand during the process — tea towels, tongs, whatever tools help — so you're not scrambling for something once the pot is simmering.

Step 3 — Prepare and simmer the dye bath

Place your black-eyed susans into the cleaned dye pot and cover them completely with water. Bring the pot to a simmer on low-medium heat and let it continue for approximately two hours. This gentle, extended simmer draws the pigment out of the flowers gradually, without overheating the dye bath and losing color intensity.

Step 4 — Monitor and maintain the dye bath

After 20 to 25 minutes of heating, take a look at the water — you should see it starting to take on a honey-like color from the dark centers of the flowers. Let the bath continue simmering for another hour, then check its progress again roughly every half hour until you're happy with the color intensity. If the water level drops during this time, top it off with rainwater so the flowers stay fully submerged, and feel free to add more black-eyed susans — or swap in fresh ones for any that have wilted — if you want a stronger color.

Step 5 — Scour, dye, and rinse the yarn

Before dyeing, scour your yarn to remove any oils, impurities, or dirt that could interfere with color absorption. Once the dye bath has reached your desired color, submerge the scoured yarn and let it soak for several hours, stirring it occasionally so the color develops evenly throughout the skein rather than settling more heavily in one spot. When you're satisfied with the color, rinse the yarn thoroughly under cool water until it runs clear, then hang it up to dry.

Frequently asked questions

What is the best method to prepare a black-eyed susan dye bath?
Place the black-eyed susans into a cleaned dye pot and cover them with water. Simmer on low-medium heat for approximately two hours to gently extract the flowers' pigment without overheating it.

How should I set up my workspace for dyeing yarn with black-eyed susans?
Keep your workstation free of contaminants that could affect the dye bath or yarn, and wash all dishes and utensils before starting. Prepare any additional supplies you'll want during the process so you aren't searching for them once the dye bath is simmering.

How do I monitor a black-eyed susan dye bath as it simmers?
After 20 to 25 minutes of heating, check the water color — it should be developing a honey-like hue from the flowers' dark centers. Let it continue simmering for another hour, then check again roughly every half hour until the color reaches the intensity you want.

What are some tips for even color distribution when dyeing yarn?
Stir the yarn occasionally while it soaks in the dye bath. If the water level drops, top it off with rainwater to keep the flowers fully covered, and add more black-eyed susans if you want to intensify the color further.
