How to Tie a Spiral Knot Bracelet with Red Agate Chips (Adjustable, About One Album Long)

Some bracelets take a weekend. This one takes about as long as one album. Put a record on, pour the red agate chips onto the table, and by the last track you will have an adjustable spiral knot bracelet on your wrist. If you have been looking up how to tie a bracelet that feels handmade in the good way, textured, earthy and a little collected, this is the one to start with.

It is the kind of piece that makes an autumn stack look collected rather than matched: warm red stones, twisted brown cord, no metal clasp. Below are 16 photographed steps, two tips you will not find in most tutorials, and answers to the sizing questions everyone asks.

What you'll need

Supplies

• 1mm hand-twisted cotton cord, for the main cord, the working cord, a short piece for the closure and one split ply for the stones
• Red agate chips, with a few clear or pale chips to soften the color transitions
• A short piece of stiff wire to use as a threading needle

Tools

• Scissors
• A soft tape measure, or a strip of paper and a ruler

Before you start: how to measure wrist size

Wrap a soft tape measure around your wrist just above the wrist bone and note the snug measurement. Add about 1/2 inch for a close fit or 1 inch for a looser one. Because this bracelet closes with a sliding knot, you only need to get close: you will fine-tune the fit on your own wrist in Step 9.

Part 1: Prepare the cords and stones

1. Step 1: Split a strand for the stones

   

   Start with 1mm hand-twisted cotton cord and a handful of red agate chips, then untwist a length of cord and pull out a single ply to use as your stone strand.

   Why it matters: Because the stone strand is the same cotton as your knotting cord, it blends into the weave and the finished bracelet reads as one material instead of two.

2. Step 2: Thread every stone before you knot

   

   Use a short piece of stiff wire as a needle and string all of your chips onto the single ply before you tie a single knot.

   Why it matters: Natural chips never come in an even color mix, so stringing them all first lets you see the whole color gradient at once and rearrange it before anything is locked in.

3. Step 3: Set up the core and working cords

   

   Lay the main cord and the beaded stone strand side by side as your core, then fix a working cord across them where the bracelet will begin.

   Why it matters: The core and stone strand travel together through the middle of the spiral, so the working cord does all the knotting and the stones stay where you put them.

Part 2: Tie the spiral knot and set the stones

4. Step 4: Start the spiral knot

   

   Begin tying spiral knots with the working cord around the core: repeat the same half knot, always starting from the same side.

   Why it matters: Repeating one half knot makes the cord twist into a spiral on its own, so you get the rope-like texture without forcing the turn.

5. Step 5: Set a stone every 0.2 to 0.3 inch

   

   After every 0.2 to 0.3 inch (about 5 to 8 mm) of spiral, lift the stone strand, slide up the next chip and nestle it into a dip of the spiral.

   Why it matters: Placing stones by measured distance rather than by eye keeps them evenly spaced all the way around the wrist.

6. Step 6: Lock the stone in and keep knotting

   

   Once the chip sits in place, keep tying spiral knots with the stone strand pressed flat against the core.

   Why it matters: Keeping the strand snug against the core stops chips from flopping sideways and keeps the spiral line smooth.

7. Step 7: Repeat: a run of knots, then a stone

   

   Keep the rhythm going with a short run of spiral knots, then the next chip into the next dip.

   Why it matters: A steady rhythm is what makes the stones look naturally scattered rather than bunched together.

8. Step 8: Check your tension as you go

   

   Every few stones, look at the spiral up close and make sure the stone strand is still tucked snugly against the core.

   Why it matters: Even tension now means the bracelet lies in a smooth circle later, with no loose loops between the stones.

9. Step 9: Try it on and adjust the length

   

   When the knotted section looks almost long enough, wrap it around your wrist and adjust the main cord until it fits.

   Why it matters: It is easiest to fix the length now, because once the closure is tied the knotted section is set.

Part 3: How to tie an adjustable bracelet closure

10. Step 10: Tie the sliding square-knot closure

    

    Cross the two ends of the main cord so they overlap, then take a new piece of cord and tie square knots over both ends to form a sliding closure.

    Why it matters: The square knots grip the two ends just enough to hold their position while still letting them slide, which is what makes the bracelet adjustable.

Part 4: How to tie a knot for a bracelet's cord ends

This finishing knot does two jobs at once: it stops the sliding closure from coming off, and it gives each end a scalloped edge that looks deliberate rather than tied off.

11. Step 11: Coil each end into a little wreath

    

    Working on one end of the main cord at a time, loop the cord around itself 5 times, the way you would coil a small olive wreath.

    Why it matters: Five coils give the end knot enough bulk to act as a stopper, so the closure cannot slide off the cord.

12. Step 12: Twist the wreath closed

    

    Hold the two tails coming out of the wreath and turn them in opposite directions as you gently pull.

    Why it matters: Turning the tails cinches the five coils down into one compact knot instead of a loose ring.

13. Step 13: Shape the scalloped finishing knot

    

    Keep turning and tightening until the coils settle into a neat, scalloped-edge finishing knot, then repeat on the other end.

    Why it matters: The scalloped edge looks finished and decorative, and it is firm enough to stop the sliding closure on both sides.

14. Step 14: Trim the tails

    

    Snip off the leftover tails beyond each knot, and your red agate cotton cord bracelet is finished.

    Why it matters: Short, tidy tails keep the knots from catching on sleeves and let the stones stay the focus.

Part 5: One technique, endless stones

15. Step 15: Lay out the before and after

    

    Set the finished bracelet beside the chips and cord you started with.

    Why it matters: Seeing a scatter of stones become something wearable is the satisfying part, and it is the photo that tells the whole story when you share your make.

16. Step 16: Swap the stone and make another

    

    Use the exact same steps with a different stone, like these picture jasper chips on natural-color cotton cord.

    Why it matters: Once you know the spiral knot and the sliding closure, every new stone and cord color becomes a new bracelet for your stack.

Frequently asked questions

How do I measure my wrist size for a bracelet?

Wrap a soft tape measure around your wrist just above the wrist bone, or use a strip of paper, mark where it overlaps and lay it against a ruler. Take the snug measurement, then add about 1/2 inch for a close fit or about 1 inch for a looser fit. With a sliding closure like the one in this tutorial, aim for a knotted section close to your wrist measurement and let the closure handle the rest.

How do I measure bracelet size on a bracelet I already own?

Lay the bracelet flat and measure from end to end, including the closure. For an adjustable bracelet, measure it twice: once slid fully closed and once fully open. Those two numbers are the range it will fit, and comparing them with your wrist measurement tells you whether it will sit snug or loose.

How do I tighten a knot bracelet?

On a sliding square-knot closure, hold the closure and pull the two cord ends outward to tighten; to loosen, hold the ends and slide the closure back toward them. The finishing knots on each end act as stoppers, so the bracelet cannot slide off. If the closure starts slipping on its own after a lot of wear, add one more square knot to give it extra grip.

Is a sliding knot the same as a slip knot for a bracelet?

Not quite, although many people search for a slip knot when they want a bracelet that slides open and shut. A true slip knot pulls loose when you tug the tail. The sliding square-knot closure in this tutorial stays put on its own and moves only when you deliberately slide it, which makes it a better everyday adjustable bracelet closure.

What does red agate mean?

In crystal traditions, red agate is associated with steadiness, courage and warmth, and it is often described as a grounding stone. Many people wear it as a small, everyday reminder of an intention, such as moving at a steady pace or staying brave through a busy season. Its meaning is symbolic: a cue to come back to, not a cure for anything.

What is the best cord for a spiral knot bracelet?

Thin cotton cord around 1mm works well because it is soft against the skin, grips each knot and shows off the spiral texture. If you split one ply from the same cord to thread your stones, the stone strand matches the knotting cord exactly and the finished bracelet looks seamless.

Prefer to wear one today?

If you would rather skip straight to wearing it, our Red Agate Spiral Knot Bracelet is the same spiral-knot design, knotted by hand and ready to slide on. Like the version in this tutorial, it is an adjustable bracelet, so it fits most wrists and layers easily with the rest of your red agate jewelry and everyday stack.
