How to Make Stain Out of Walnuts

Making stain out of walnuts comes down to extracting the natural tannins and juglone found in the hulls.
 
Here’s the whole process, step by step.
 

1. Gather Black Walnut Hulls

The best material for making stain out of walnuts is the green outer hull, not the hard shell inside.
 
Black walnut hulls are packed with juglone, the compound that gives walnut stain its deep, rich brown color.
 
You can collect them in late summer and early fall when the hulls are still green or just starting to turn brown and soft.
 
Wear gloves while handling them because walnut hulls will stain your hands for days.
 

2. Chop or Crush the Hulls

Once you have your hulls, chop or crush them into smaller pieces.
 
The more surface area you expose, the more color you’ll pull out when making stain out of walnuts.
 
You can use a hammer, a blender, or just stomp on them in a bucket.
 

3. Simmer the Hulls in Water

Place your crushed hulls in a large pot and cover them with water.
 
Bring the water to a simmer and let it go for one to two hours, stirring occasionally.
 
The longer you simmer, the darker your walnut stain will become.
 
For a really concentrated stain, you can simmer for several hours or even let the mixture sit overnight.
 

4. Strain the Liquid

Once you’re happy with the color, strain out the hulls using a cheesecloth or fine mesh strainer.
 
What’s left is your homemade walnut stain, ready to use.
 

5. Add a Mordant for Fabric

If you’re making stain out of walnuts for fabric, add a mordant like alum, vinegar, or salt to help the color bind.
 
This step isn’t necessary for wood, but it makes a big difference on textiles.
 

Ways to Use Your Walnut Stain

Once you’ve made stain out of walnuts, you can put it to work in several ways.
 

1. Staining Wood

Walnut stain gives wood a warm, antique brown finish that looks especially good on maple, oak, and pine.
 
Brush it on, let it soak in, then wipe off the excess for an even tone.
 

2. Dyeing Fabric

Making stain out of walnuts is a favorite among natural dyers because it works on cotton, linen, wool, and silk.
 
Soak your fabric in the dye bath, then let it dry and set with heat for the best results.
 

3. Aging Paper and Crafts

You can also use walnut stain to give paper, tags, and craft projects a vintage, weathered look.
 
Just brush it on lightly and let it dry.
 

4. Touching Up Furniture

A little walnut stain is perfect for hiding scratches and scuffs on dark wood furniture.
 
Dip a cloth in the stain and dab it onto the damaged spot.
 

Tips for Making Stain Out of Walnuts

A few simple tricks will help you get better results when making stain out of walnuts.
 

1. Use Fresh Hulls When Possible

Fresh green hulls give the strongest color for walnut stain.
 
If you can only find dried hulls, use more of them and simmer longer.
 

2. Test on Scrap First

Always test your walnut stain on a scrap piece of wood or fabric before applying it to your real project.
 
Different materials absorb stain differently.
 

3. Add a Little Rust for Deeper Color

Old-timers toss a few rusty nails into the pot when making stain out of walnuts.
 
The iron reacts with the tannins and darkens the stain nicely.
 

4. Store It Properly

Keep your finished walnut stain in a sealed jar in a cool, dark place.
 
It’ll last for months, and you can always reheat it if it thickens.
 

5. Be Careful with Plants

Juglone is toxic to many plants, so don’t dump leftover walnut stain water in your garden beds.
 

So, How Do You Make Stain Out of Walnuts?

You make stain out of walnuts by simmering crushed black walnut hulls in water and straining the liquid.
 
This simple process gives you a rich, natural walnut stain for wood, fabric, and crafts.
 
Once you learn how to make stain out of walnuts, you’ll never look at those fallen hulls the same way again.
 
Give it a try, and enjoy the deep, beautiful color that only walnut stain can deliver.
