Natural dyeing has been practiced for centuries, using readily available plants, fruits, and vegetables to color fabric. One of the most versatile and eco-friendly methods for achieving warm, earthy tones is dyeing fabric with onion skins. Onion skins—both yellow and red—offer a natural, chemical-free way to dye textiles, creating beautiful shades ranging from golden yellows to rich rust oranges.
In this comprehensive guide, we will explore various methods to dye fabric with onion skins, step-by-step instructions for each, and tips for achieving the best results. Whether you’re an experienced fabric dyer or a beginner, onion skin dyeing is an easy, rewarding project that produces stunning, unique results.

Why Use Onion Skins for Dyeing Fabric?
There are many reasons why onion skins are an excellent natural dye source:
- Sustainability: Onion skins are a byproduct of cooking, making them an eco-friendly and waste-reducing option for dyeing.
- Non-Toxic: Onion skins are completely natural and non-toxic, making them a safe alternative to chemical dyes.
- Rich Colors: Yellow onion skins produce a range of warm colors from soft yellows to deep orange, while red onion skins can yield pinks, purples, and rust tones.
- Ease of Use: Onion skin dyeing is beginner-friendly and doesn’t require complicated processes or special equipment.
What Fabrics Work Best for Onion Skin Dyeing?
Natural fabrics are the best choice for dyeing with onion skins, as they absorb the dye better than synthetic fabrics. Some excellent options include:
- Cotton: A versatile, affordable fabric that takes the dye well.
- Linen: Another natural fabric that creates beautiful, earthy tones.
- Silk: Silk absorbs the dye and produces vibrant, rich colors.
- Wool: Wool dyes well with onion skins, creating soft, warm hues.
Synthetic fabrics like polyester or nylon do not take natural dyes as effectively, often resulting in uneven or faded colors. Always use 100% natural fibers for the best results.
Collecting and Preparing Onion Skins for Dyeing
To begin, you’ll need to collect enough onion skins to create a strong dye bath. Save the skins from your cooking, or ask your local grocery store or farmers market for discarded onion peels.
How Much Onion Skin Do You Need?
For best results, aim for about one large handful of onion skins per half pound of fabric. This can be adjusted depending on how strong you want the color to be. The more onion skins you use, the more vibrant the color will be.
Preparing Onion Skins for Dyeing
Before starting the dyeing process, it’s essential to prepare the onion skins:
- Rinse the Skins: Gently rinse the onion skins under cool water to remove any dirt or residue.
- Tear or Cut: Tear or cut the skins into smaller pieces to help them release their dye more effectively during the boiling process.
Preparing the Fabric for Dyeing
To ensure the fabric absorbs the dye evenly, it’s essential to properly prepare the material:
- Wash the Fabric: Wash your fabric with a mild detergent to remove any dirt, oils, or chemical finishes. Avoid using fabric softeners, as they may prevent the fabric from absorbing the dye.
- Mordanting (Optional): Mordanting is the process of pre-treating fabric with a fixative to help the dye bond with the fibers. While onion skins produce a strong, lasting color on their own, adding a mordant like alum can make the dye more durable and vibrant. Soak the fabric in a solution of 1 tablespoon alum per gallon of water for an hour, then rinse and dry.
Different Ways to Dye Fabric with Onion Skins
There are a few different methods you can use to dye fabric with onion skins, each offering a unique result. Below, we’ll explore hot dyeing, cold dyeing, and a tie-dye technique for creating patterns.
1. Hot Dye Method
The hot dye method is the most common way to dye fabric with onion skins. It uses heat to extract the dye from the skins and quickly transfers it to the fabric.
What You’ll Need:
- Onion skins (yellow or red)
- Large pot
- Water
- Stirring spoon
- Gloves
- Strainer or cheesecloth
- Optional: Mordant (alum or vinegar)
Step-by-Step Instructions:
- Prepare the Dye Bath: Place the onion skins into a large pot and fill it with water. Use about 1 part onion skins to 2 parts water. Bring the water to a boil, then reduce to a simmer. Let the onion skins simmer for at least 30–60 minutes, or until the water turns a deep golden or reddish hue, depending on the onion type.
- Strain the Dye: Once the dye has reached the desired color, strain the onion skins from the liquid using a strainer or cheesecloth. You now have a concentrated dye bath.
- Dye the Fabric: Submerge your pre-washed, wet fabric into the dye bath. Stir the fabric occasionally to ensure even coverage. Simmer the fabric in the dye for at least 30 minutes to an hour. For a deeper color, you can allow the fabric to soak for several hours or even overnight.
- Rinse and Dry: Once the fabric has reached your desired color, remove it from the dye bath and rinse it in cool water until the water runs clear. Hang the fabric to air dry, out of direct sunlight.
- Set the Dye: You can set the color by soaking the fabric in a vinegar-water solution (1 part vinegar to 4 parts water) for 30 minutes before rinsing and drying.
2. Cold Dye Method
The cold dye method offers a more subtle, gradual dyeing process, perfect for delicate fabrics or lighter shades.
What You’ll Need:
- Onion skins (yellow or red)
- Water
- Large container
- Gloves
- Strainer
Step-by-Step Instructions:
- Create the Dye Bath: Similar to the hot method, place onion skins in a pot and add water. However, instead of boiling, simply allow the skins to steep in cold water for at least 24 hours. This slow-release method gently extracts the dye over time.
- Strain the Skins: After 24–48 hours, strain the onion skins from the dye bath.
- Submerge the Fabric: Place your pre-washed, damp fabric into the cold dye bath, making sure it’s fully submerged. Let it soak for at least 24 hours, stirring occasionally for even dyeing.
- Rinse and Dry: Once the fabric has achieved the desired color, remove it from the dye bath and rinse it in cold water until the water runs clear. Hang to dry.
- Optional Setting: To set the dye, soak the fabric in a vinegar-water solution for 30 minutes before rinsing and drying.
3. Tie-Dye or Pattern Dyeing
For a creative spin, you can use onion skins to create tie-dye patterns or other designs on fabric. This technique gives your dyed fabric a more artistic, handmade look.
What You’ll Need:
- Onion skins (yellow or red)
- Rubber bands or string
- Gloves
- Large pot
- Strainer
Step-by-Step Instructions:
- Prepare the Fabric: Start with damp, pre-washed fabric. Use rubber bands or string to tie sections of the fabric, creating the areas that will resist the dye and form patterns. The tighter you bind the fabric, the more defined the pattern will be.
- Dye Bath Preparation: Prepare a hot dye bath using the same method as the hot dye method above.
- Dye the Fabric: Submerge the tied fabric into the dye bath and let it simmer for 30–60 minutes, depending on the desired intensity of the color. Stir occasionally to ensure the fabric is evenly exposed to the dye.
- Rinse and Untie: Once the fabric has reached the desired color, remove it from the dye bath and rinse in cold water. Carefully remove the rubber bands or string to reveal the patterns.
- Set and Dry: Set the dye using a vinegar-water soak if desired, and hang the fabric to dry.
Color Variations with Onion Skins
The color produced by onion skin dyeing can vary based on several factors:
- Yellow Onion Skins: These skins typically produce warm, golden-yellow to burnt orange shades.
- Red Onion Skins: Red onion skins yield a range of colors from rusty oranges to pinks and purples, though these tones may vary based on the fabric type and dyeing method.
- Dyeing Time: The longer the fabric is left in the dye bath, the richer and deeper the color will be.
- Mordants: Mordants like alum or vinegar can alter the final color, making it more intense or long-lasting.
Caring for Onion Skin-Dyed Fabric
Once your fabric is dyed, it’s important to care for it properly to maintain the vibrancy of the color. Here are a few tips:
- Hand Wash or Gentle Cycle: Natural dyes are more delicate than synthetic ones, so it’s best to hand wash your fabric or use a gentle cycle in the washing machine.
- Cold Water: Always wash dyed fabrics in cold water to prevent the color from fading.
- Air Dry: Avoid using a dryer, as heat can cause the natural dye to fade more quickly. Hang your fabric to air dry out of direct sunlight.
