How to Make Walnut Stain From Black Walnuts

Learning how to make walnut stain from black walnuts starts with gathering the right part of the tree.
 
The hulls, not the hard shells or the nutmeat inside, are what give you that gorgeous, ink-like brown dye.
 
Let’s break down the steps so you can make walnut stain from black walnuts without any guesswork.
 

1. Harvest the Black Walnut Hulls

The first step in how to make walnut stain from black walnuts is collecting the hulls in late summer or early fall.
 
Look for black walnuts that have fallen from the tree, and you’ll notice the outer hulls turn from green to a dark, mushy black.
 
That’s when they’re packed with the most pigment for making walnut stain.
 
Always wear gloves when you handle black walnut hulls because the juglone inside will stain your hands for days.
 

2. Simmer the Hulls to Extract the Dye

Once you have your hulls, making walnut stain from black walnuts means simmering them in water.
 
Place the hulls in a large pot, cover them with water, and bring everything to a gentle boil.
 
Let the black walnuts simmer for an hour or more until the liquid turns a deep, dark brown.
 
The longer you simmer, the darker your walnut stain will become.
 

3. Strain and Reduce the Liquid

After simmering, strain out the hulls and keep the dark liquid, which is your walnut stain.
 
If you want a stronger stain from black walnuts, simply simmer the liquid down further to concentrate the color.
 
This step is key when you make walnut stain from black walnuts because a thicker dye gives you a richer finish on wood.
 

4. Add a Binder for a Durable Finish

Plain walnut stain from black walnuts works, but it can fade without a binder.
 
Stir in a small amount of vinegar or a bit of shellac to help the stain from black walnuts bond with the wood.
 
This extra step in how to make walnut stain from black walnuts gives you a longer-lasting, more even color.
