Natural Dye Tutorial: Yellow From Osage Orange Wood
Natural Dyeing with Osage Orange Wood: A Bright Yellow from the Hedge Apple Tree
If you’re looking to explore natural dyes that yield vibrant, lightfast colors, Osage orange (Maclura pomifera) is one of the best ways to get a true, rich yellow. This bright yellow wood has been used for centuries by fiber artists and woodworkers, and is still beloved today by fiber artists seeking deep, golden hues. In this post, I’ll walk you through my simple recipe for making a yellow dye bath using Osage orange wood shavings—and show you how I go from harvesting wind-fallen branches to hanging freshly dyed wool yarn on the line to dry.
Osage orange (also called hedge apple or horse apple) is a rewarding plant to work with. It’s a substantive dye, which means it can yield good colors on its own, but a mordant like aluminum sulfate (for wool, silk, and other protein fibers) or tannins and potassium aluminum sulfate (for cellulose fibers like cotton or linen) will aid in producing richer colors.
What Is Osage Orange?
Osage orange trees are native to the central United States and have a fascinating history. Once used for wagon wheels, fences, and the famous Osage bow, the wood is incredibly strong and rot-resistant. The heartwood of the Osage orange tree is especially valued for its dye potential. When you chip, shave, or saw the wood, and then soak it in hot water, it releases a distinctive yellow dye that can create shades ranging from soft yellow greens to deep, bright yellow depending on your mordant, fiber, and dye concentration.
Some natural dyers even overdye Osage with other dyes—like indigo—for a wide range of colors, including bright emerald and olive greens. It is also an excellent complimentary color for use alongside black oak, walnut, or even cochineal.
Harvesting Osage Wood
The best way to gather your dye material for free is to look for a fallen limb from an Osage tree. After wind or storm damage, these tough trees may shed a branch or two. A friend called me when that happened at her place, and my husband and I went over and cut the limb into manageable pieces with a chainsaw.
From there, I split the logs with a hatchet and sledgehammer (this wood is incredibly tough) and use a whittling knife to shave thin curls from the heartwood. You could also use your preferred method of creating wood shavings or sawdust. Some people prefer chipping the wood, and Osage sawdust from milling or woodworking projects works just as well too.
If you’re using shavings, store them in an airtight container until you’re ready to dye. Osage orange shavings hold their color well over time when kept out of direct sunlight.
Prepping Your Fiber: The Mordant Bath
Before dyeing, you’ll need to mordant your fabric or yarn for best results. This helps the dye bond with the fiber for better color results and long-term durability. For cellulose fibers, I recommend potassium aluminum sulfate. For protein fibers like wool yarn, aluminum sulfate is my go-to. Some dyers also add a form of tannic acid like oak gall powder.
You can read a helpful protien fibers mordanting guide, or a cellulose fabric mordanting guide, to learn appropriate mordant ratios, and how to prepare your fiber based on the type.
Making the Dye Bath
Once your fiber is pre-mordanted and ready, it’s time to extract that beautiful yellow color.
Ingredients:
- Osage orange shavings or sawdust (around 1 oz of shavings per 1 oz of dry fiber)
- Enough water to cover the dye material
- A large dye pot (non-reactive)
- Mordanted fiber
Simple Steps:
- Soak the Osage wood: Place your wood chips or shavings into your dye pot and cover with hot water. Let this soak overnight for maximum color extraction.
- Simmer the dye: The next day, bring the mixture to a low boil over medium heat. Simmer for 1–2 hours. You’ll notice a dramatic color change as the water shifts to a deep amber or orange color. This is your dye liquid.
- Soak the fiber: While your dye pot is simmering, soak your mordanted fabric or yarn in very hot water in a separate pot. This helps the dye absorb evenly.
- Strain the bath: Remove the wood chips by pouring the dyebath through a strainer into a second dye pot. Some dyers reuse their used wood chips for a second extraction, which may create lighter shades.
- Heat the dyebath: Return the dye pot full of amber colored liquid to the stove and heat on medium heat until the dyebath is steamy.
- Dye your fiber: Add your hot, wet fiber to the strained dye bath. Simmer very gently (don’t boil!) for about an hour. If you are working with loose wool, do your best not to agitate the fibers while wet to avoid felting it. When your fiber has become deep yellow, turn off the heat and let it cool in the dye liquid for several hours or overnight for the deepest shades.
- Final gentle wash: Rinse the fiber in same-temperature water until the water runs clear. Hang to dry away from direct sunlight.
The Results: Bright Golden Yellow
The resulting color from Osage orange dye can range from soft yellow to a vivid, bright yellow depending on dye concentration, mordant choice, and fiber type. Wool yarn often yields the most vibrant color, while cotton fabric may come out in lighter shades unless mordanted well.
Tips for Dyeing with Osage Orange
- Use the heartwood: The deeper the color of the wood, the stronger the dye. Avoid bark or outer wood if possible.
- More dye = deeper shades: If you want intense color, increase the amount of osage orange shavings relative to your fabric weight.
- Try blending colors: Mix Osage with cochineal for coral pinks, or over-dye with indigo for mossy greens.
- Label your samples: Keep a dye journal to track dye concentration, fiber type, and mordant for next time.
- Store extra dye: You can store leftover dye liquid in an airtight container in the fridge for a week or two.
Where to Find Osage Orange
If you don’t have an Osage tree nearby, some suppliers sell Osage orange sawdust or shavings online. Check natural dye stores like Maiwa or Dharma Trading Co. You can also look locally—woodworkers who specialize in bow-making or custom wood finishes and techniques sometimes have leftover Osage wood to share.
A Natural Alternative to Chemical Dyes
Using natural dyes like Osage orange is a beautiful way to connect with the land, avoid synthetic dyes, and create color results that are unique and personal. Check out my other natural dye tutorials below!
