You’re standing there with a beautiful piece of cord and a handful of beads, but you've got no clue how to actually make it wearable. It's frustrating. Most people just tie a basic overhand knot and hope for the best, only to find the necklace sits way too high or the bracelet falls off in the car. That's where the sliding knot comes in. It’s the industry standard for adjustable jewelry, and honestly, once you learn it, you’ll never go back to metal clasps that tarnish and break.
The beauty of a sliding knot—often specifically the double fisherman’s knot or a barrel variation—is that it relies on friction rather than a permanent bond. It’s physics in action. You’re essentially creating a tunnel of cord that another piece of cord can travel through. It stays put when you want it to, but moves when you give it a firm tug.
Why Most People Fail at the Sliding Knot
Most beginners overthink the direction of the wraps. If you wrap the cord toward the jewelry piece instead of away from it, the whole thing unspools the second you try to tighten it. It's annoying. You also have to consider the material. Trying to tie a sliding knot using cheap, slippery nylon from a big-box craft store is a recipe for disaster. It won't hold. You need something with a bit of "tooth"—think waxed polyester, leather cord, or even hemp.

I’ve seen people try to use this on paracord for heavy-duty survival gear, and while it works, the thickness makes the knot look like a giant lumpy grape on your wrist. Scale matters. For a sleek, professional look, 1mm or 1.5mm cord is the sweet spot.
The Step-by-Step Reality of the Double Sliding Knot
Let’s get into the actual mechanics. Forget the diagrams that look like a bowl of spaghetti. We’re going to do this one side at a time.
First, lay your cord out in a circle so the ends overlap by about four or five inches. This overlap is your "working zone." Grab the right-hand tail. You’re going to loop it over the main cord, creating a small circle. Now, wrap that tail around both strands of cord—the main line and itself—two or three times.
Here is the secret: wrap back toward the loop you just made.
Once you’ve done your wraps, tuck the end of the tail through those loops. Pull it tight. You’ve just created your first "slider." Now, flip the whole thing over and do the exact same thing with the other tail on the other side.
When you pull the two knots away from each other, the necklace gets smaller. Pull the main cords, and the knots slide together, making the necklace larger. It’s elegant. It’s simple. And if you do it right, it won't ever come undone on its own.
The Waxed Cord Advantage
If you're using waxed Irish linen or a high-end waxed polyester like Ritza Tiger thread (which is technically for leatherwork but amazing for jewelry), the wax acts as a natural brake. It provides just enough resistance so the knot doesn't "creep" throughout the day. If your knot feels too loose, you can actually add a tiny bit of beeswax to the cord before you tie it.
Don't use glue.
Seriously, I see so many tutorials suggesting a drop of superglue on the knot. Don't do it. Superglue makes the cord brittle and can actually "wick" into the main line, freezing the sliding mechanism entirely. If you’re worried about the tail of the knot fraying, use a thread burner or a lighter to very carefully melt the tip of the cord into a small "mushroom" shape that sits flush against the knot.
Common Mistakes That Ruin the "Slide"
One of the biggest headaches is the "ghost knot." This happens when you accidentally tie the sliding knot around the other cord, but then snag a tiny fiber of the interior cord with your needle or the tail end. Now it's a fixed knot. It’s stuck. You’ll know you did this if one side moves and the other feels like it's welded shut.
- Tension is everything: If you pull the wraps too tight during the tying process, you won't be able to move the knot at all.
- The "Tail" Length: Don't trim your tails too short. Leave about 2mm. If you cut it flush, the knot might unravel when the cord stretches over time.
- Cord Consistency: If one end of your cord is frayed or thicker than the rest, it’s going to catch inside the knot. Always use a fresh, clean cut.
Advanced Variation: The Triple Barrel
If you’re working with very thin silk or high-sheen nylon, a double wrap might not be enough. You’ll find the weight of a heavy pendant slowly pulls the knots together until the necklace is a choker. In this case, go for a triple barrel. It’s the same process, just three wraps instead of two. It creates a longer, more decorative knot that looks intentional rather than just a utility fix.

Designers like Chan Luu have made entire careers out of these styles. They aren't just for "boho" looks anymore; you'll see sliding knots on high-end gold charms and luxury silk cords in boutiques from New York to Paris.
Choosing the Right Cord for the Job
Not all string is created equal. If you're making something that's going to get wet—like a "surf" bracelet—you absolutely must avoid cotton. Cotton absorbs water, swells, and then rots. Your sliding knot will become a permanent, soggy mess within a month.
Go for S-Lon or C-Lon cord. These are specialized nylon monofilaments that are incredibly strong and come in hundreds of colors. They have a consistent diameter, which is the most important factor when learning how to tie a sliding knot. If the cord varies in thickness, the slide will be jerky and unsatisfying.
For leather, stick to "round" leather cord. Flat suede cord is a nightmare for sliding knots because it twists and binds. 1.5mm round leather is the gold standard for a reason. It has enough grip to hold the knot but enough smooth surface area to allow for a clean glide.
Professional Finishing Touches
Once you've mastered the knot, look at the ends of your cord. A raw, melted plastic blob is ugly. Instead, try sliding a small "stopper bead" onto the tail before you melt or knot the end. This keeps the tail from accidentally pulling back through the sliding knot if you open the jewelry too wide.
Another pro tip: before you tighten the wraps of your sliding knot for the final time, insert a small needle or a toothpick into the center of the wraps. This ensures you leave enough internal "room" for the main cord to slide through once the needle is removed. It’s a trick used by professional macramé artists to ensure perfect tension every single time.

Troubleshooting a Stuck Knot
If you’ve finished your piece and the knot won't budge, don't reach for the scissors yet. Sometimes the cord just needs to be "broken in." Take a pair of pliers—smooth jawed, so you don't mar the cord—and gently grip the knot. Give it a tiny squeeze from a few different angles. This can often compress the internal wraps just enough to release the friction.
If that fails, check the "exit hole" where the main cord leaves the knot. Sometimes a tiny stray fiber gets caught there. A pair of fine-point tweezers can usually clear the obstruction.
Next Steps for Your Projects
Now that you've got the theory and the technique down, the best way to get this into your muscle memory is repetition. Take two feet of scrap cord and tie/untie the knot ten times while watching something on TV. Don't worry about making jewelry yet; just focus on the tension of the wraps.
Once your fingers know the movement, try it with different materials. Notice how leather requires more force than nylon. Experiment with adding a single decorative bead between the two sliding knots to create a centered focal point on the back of a necklace. This keeps the knots symmetrical and prevents them from sliding all the way to the front of your neck.
For your first real project, start with a simple adjustable bracelet. It’s smaller, easier to handle, and allows you to test the durability of the knot throughout a normal day of wear. If the knot holds through a workout or a shower, you’ve mastered the tension. From there, you can move on to multi-strand designs or complex lariats that use the sliding knot as a primary design element.
