How To Dye Raw Wool

Dyeing raw wool is a fun and simple project the whole homesteading family can enjoy doing together. You can probably dye the wool sheared from your sheep with ingredients you already have stockpiled in your kitchen.

As already noted, dry wool takes either natural or artificial dye extremely poorly. If you plan on drying the wool it is best to take is straight from the scouring bath into the dying process.

You can wet dry wool for dying, but the more wool is exposed to warm water and heat, the better the chance that it will welt felt and mat together so it is unusable for manipulation by fiber artists.

Wool Dying Basics

There are a myriad of ingredients you can use to dye wool. I often use non-sweetened Kool-Aid, food coloring, various spices, and even vegetables, to mix colors. No matter what type of dying agent you choose to use, a mordant will always be necessary.

A mordant, or fixative, prepares the wool to accept the dye. The mordant does not fix the dye. The mixture of wool and the coloring agent must go through a heating process to actually fix the dye permanently onto the sheep fleece.

Salt is often used as a mordant when using berries for wool dye. Distilled white vinegar is typically used as a mordant when working with spices, flowers, vegetables, food coloring, and non-sweetened Kool-Aid as dyes. I often place a teaspoon of salt in with my vinegar mordant mixture to cover all my bases and help ensure the dye is set firmly into the raw wool.

How much of the fixative is needed depends upon how much wool is being dyed, and how the mixture of wool and dye will be heated. Generally, if you are simmering the mixture on the stove, more mordant is necessary.

I had intended to demonstrate the simmering process in this wool dyeing tutorial, but the process is far more time consuming than simply using a microwave – especially when dying a large batch of wool in multiple colors, as I was doing. Heating a wool dye mixture takes only about 5 minutes when using a microwave but takes a minimum of one hour (usually two if you want a deep, dark, or vibrant color) when heating the wool dye on a stove.

The end result whether you use a microwave or stovetop is the same, in my opinion. But, I did detail the stovetop method of heating for homesteading folks who prefer not to use microwaves.

How to Dye Wool With Non-Sweetened Kool-Aid


  • 4 packets of non-sweetened Kool-Aid for each standard paper plate amount of wool being dyed – about four cups of wool
  • 2 tablespoons of distilled white vinegar per small color batch.
  • 1 teaspoon of standard table salt per small color batch.
  • Large glass measuring cup or microwave safe bowl.
  • Stirring spoon – if you use wood spoons or a rubber ended spoon the dye will likely adhere to it permanently.
  • Latex gloves – optional. Kool-Aid does not stain as bad or for as long as other natural or synthetic dyes, but it will discolor your hands at least slightly.
  • Warm water
  • Sink or plastic tub
  • Strainer – the dye could temporarily or permanently discolor the strainer.


Step 1: Pour the distilled white vinegar and the salt in the glass measuring cup or microwave safe bowl.

Step 2: Stir to combine.

Step 3: Open the Kool-Aid packets, and pour them into the measuring cup or bowl.

Step 4: Stir to combine thoroughly.

Step 5: Place the still damp wool into the mixture. Tap it down slowly to saturate. You have to be very careful not to handle the now fully saturated wool too much, or wet felting will occur. It is not uncommon for more small debris particles to work their way out of the wool during the dying process. Simply pick them out with your fingers and throw them away.

Step 6: Now, flip the wool over – handling it carefully and gently, and make sure the top side is soaked fully into the Kool-Aid dye, as well.

Step 7: Place the measuring cup or bowl into the microwave for 5 to 6 minutes. You can also set the timer for 2 minute increments to check the progress, and gently and carefully (wool will be incredibly hot) flip the wool over to soak on the other side – optional.

Step 8: Remove the wool from the microwave and pour it gently into the strainer you have placed in the sink to drain away the dye mixture.

Step 9: Allow the wool to drain and cool for at least two minutes.

Step 10: Place the dyed wool onto a towel, baking rack, or paper plate, and allow it to air dry completely. Unless you are using a baking rack, you will need to turn the wool over multiple times to ensure both sides are drying evenly, and to pour away any excess dye that will work its way out of the dense wool.

Tips and Hints

  • It can take 1-3 days for the wool to dry completely before it can be stored or used in needle felting projects.
  • If the color of the dye bath is not pale, the wool has not soaked up enough of the dye to create an even color throughout or to be a bold color when dried. If the dye bath mixture is still dark after about 5 to 6 minutes in the microwave, put it back in for another 2 minutes.
  • If the dye bath is still not pale after the additional two minutes in the microwave, consider using a little more vinegar and salt in the next batch, or heating the vinegar so it is warm – not hot, when using it as a mordant before adding the Kool-Aid dye (or any dying agent except berries) into the bowl.
  • To use the stovetop to dye the wool with Kool-Aid instead of the microwave, follow the heating instructions in the produce dying section below.

How to Dye Wool With Fruits and Vegetables

There are a plethora of different type of vegetables you can use to dye wool – or basically any natural fabric.

Best Fruits and Veggies for Wool Dying:

Red Cabbage – no mordant neededBlack Raspberries
Red OnionsBeets


  1. Finely chop up the chosen produce and place it in a cook pot. It is best to use either stainless steel or dedicate a cook pot just for dying, because it will become permanently stained.
  2. Place the chopped produce in the cook pot.
  3. Pour twice as much water as the fruits or vegetables you will be using as a natural dye.
  4. Bring the water to a rolling boil.
  5. Turn down the heat to a simmer, and let the mixture steep for at least one hour.
  6. Remove the pot from the stove, and pour the mixture through a strainer you have placed in your sink with another pot beneath it to capture your dye.
  7. Now it is time to add a mordant to the dye. If using salt (which works best with berries) dissolve ½ cup of salt for every 8 cups of water used in the dye. If using distilled white vinegar, use one part for every for parts of water used in the dye mixture.
  8. Once the mordant has been added to the dye mixture and stirred thoroughly to combine, immerse your raw wool into the pot, as well. Do not place so much wool into the pot that is cannot move about freely, or leave any part unsubmerged once you gently push it down (wearing gloves) into the mixture.
  9. Simmer the dye mixture with the wool immersed in it for at least 60 minutes. If you want bold, dark, or vibrant color, simmer up to two hours.
  10. Once you are satisfied with the color the wool has taken one, pour the pot through the strainer once again.
  11. Remove the wool once it has cooled enough to touch and place on a paper plate, towel, or drying rack. It will typically take between 1 to 3 days for the dyed wool to thoroughly dry, as noted above. Remember, if the wool is drying on a towel or paper plate, it will need to be flipped over periodically, and any dripping dye poured away.
  12. To dye wool naturally with fruits and vegetables in a microwave to speed up the process, follow the heating instructions in the Kool-Aid dying section.

Wool Dyeing With Flowers Herbs, Flower, Roots, and Bark

You can dye wool with either fresh or dried flowers and herbs. Some fans of natural homemade dyes contend that using fresh flowers and herbs brings a more vibrant color to the dye – and I tend to agree.

To make a dye using flowers, herbs, roots, or bark, simply chop the items finely, and follow the dye preparation steps noted above in the fruits and vegetables section to create your coloring mixture.

Once you choose a heat source (microwave or stovetop) follow those already outlined directions, process your raw wool in the dye and lay it out to thoroughly dry before use.

The color of the natural item does not necessarily dictate the hue it will create when processed into a dye. Typically, the more of the natural dying agent you use, the darker or more vibrant the shade will be on the wool.

Review the list below to discover some popular and commonly available naturally growing dye ingredients, and the shades they create in a dye mixture.

How to Dye Wool with Food Coloring


  • Food Coloring – 4 tablespoons per every quart of water used
  • Standard Table Salt – 1 cup per ever gallon of water used
  • Water
  • Stainless steel cook pot or a cook pot that has been dedicated for dying
  • Spoon that will not stain or has been dedicated for dying projects
  • Latex gloves


  1. Fill the pot up with enough water to cover the amount of raw wool you are going to dye. Don’t forget to measure the amount of water used so you can determine how much salt and food coloring you need.
  2. Squeeze in the food coloring. If mixing several color together to create a specific shade, you must count each drop of every color used towards your total per quart allotment.
  3. Pour in the salt.
  4. Heat the mixture on the stovetop over low to medium heat – just to a simmer – or put the mixture into a microwave safe bowl and heat it for about 2 minutes.
  5. Put the wool into the dye bath and carefully submerge.
  6. Allow the wool to sit in the dye mixture for for about 20 minutes while it is still simmering on the stovetop or put it into the microwave for about 5 minutes.
  7. Once the mixture is removed from the heat source, strain it in the sink.
  8. Gently rinse the dyed wool in water, and lay it out to dry as noted in above instructions.

A Little Bit of History

All wool and fabric used to be hand-dyed naturally. It was not until the mid-1800s when a very young chemist, 18 year old William Henry Perkin, accidentally created the first synthetic dye. Perkin was working to create artificial quinine to treat people stricken with malaria when he wound up with a beautiful dark dye instead.

Perkin named the dye, mauveine – which eventually became known as mauve. This accidental invention provoked an entirely new industry….virtually killing an old cottage one in the process. Thousands of natural hand dyers across the globe were soon forced to find another way to make a living.

Thanks to the burgeoning homesteading and living naturally movements, this nearly forgotten “business” is springing back to life in kitchens around the world.

Are You Ready to Dye Your Own Wool?

Cleaning and dyeing raw wool are great family projects. If you are homeschooling children on your homestead you can use the project to teach them about using all parts of the animals you are raising, measuring skills, sink or float lessons for young children, learning their colors,telling time lessons, teaching fiber handicrafts, and entrepreneurial skill building if the wool will be marketed for sale.

  1. Just what I have been looking for! Microwave dyeing. Did I miss the instructions in how to do it with spices? How much do I put in? When?

    Also, will it hurt or help if I let the wool sit in the dye overnight? Brighter colors?

  2. I think it’s wonderful that young people like you are doing all these natural things. I learned to spin and dye yarn in the early 1970’s and we did all the things you are learning about now. My friends and I had a little trouble finding someone who knew how to spin to teach us as there was no internet then and most of the women who knew how to spin had died. It was truly a dying (no pun intended) art then. We didn’t know about kool-aid and food coloring so we did all our dyeing with natural materials or chemical dyes.
