What you’ll learn
Knots You’ll Need
Just three beginner knots build the whole strap. If you’ve made a keychain or small wall hanging, you likely know all of them already.
Gathering Knot + Basics
The gathering knot tidies the clasp ends — covered in the essentials guide.
Learn knotsMaterials & Tools
A short, functional list. For a strap that’s comfortable on your shoulder and strong enough to carry a bag, a soft-but-sturdy 3mm cotton cord is the key choice.
Cord & Materials
- 3mm single-strand cotton cord — soft, pliable, and strong. About 13.5 meters total (see cord lengths below). A tightly-twisted recycled cotton holds up beautifully under weight. Shop 3mm cotton cord →
- 2 lobster clasps — one for each end, so the strap clips onto bags, cameras, and rings. A swivel-style clasp prevents twisting.
Tools
- Sharp fabric scissors — the rose gold pair I use daily.
- Measuring tape — accurate cord lengths matter for a strap.
- Optional: tape or a clip to anchor the clasp while you knot.

Full Video Tutorial
This is the complete step-by-step video for the macramé strap. Watch the clasp attachment (Steps 2–3) once before you start — it’s the trickiest part, and it’s much easier after you’ve seen it.
Step-by-Step Instructions
Six steps in two phases: attach your cords and first clasp, then knot the strap body and finish the second clasp. The square-knot body is the longest part — put on a podcast.
Steps 1–3: Attach cords & clasps
Accurate cord lengths are everything for a strap. Measure twice, cut once — running short mid-strap means starting over.
- Cut 2 strands of cord to 255" (650 cm) each.
Step 2: Create the first loop and attach the clasp
The loop is how the strap grips the clasp. Get this first one snug and even; the second cord will mirror it.
- Measure 60" (150 cm) from one end of a cord and create a loop at that point.
- Attach the loop to a lobster clasp using a Lark's Head knot, leaving the shorter end of the cord on the right.
Step 3: Mirror the loop on the second cord
Mirroring the second cord keeps the strap symmetrical and balanced under weight.
- Repeat the same process with the second cord on the right side, mirroring the first.
- The two middle cord ends should both be 60" (150 cm) long.

This is the long, meditative part — rows of square knots form the body. Consistent tension is what makes a strap look professional.
- Move 1.5" (4 cm) down from the clasp and start tying a series of Square knots.
Step 5: Attach the second clasp with lark's head knots
Vertical lark’s head knots wrap the strap cleanly onto the second clasp. Leave a little space so it sits neatly.
- Use the outer two cords to tie Vertical Lark's Head knots onto the second lobster clasp.Leave 1.5" (4 cm) of space between the last Square knot and the Lark's Head knots.
Step 6: Finish with a gathering knot
The gathering knot tidies the ends near the clasp and locks everything in place. Wrap it firm — it carries the load.
- Take a 20" (50 cm) strand of cord and tie a Gathering knot in the gap left near the clasp.
- Repeat this step on the other side, then trim off any excess cord.
Ways to Use Your Macramé Strap
The clasps are the magic — one strap clips onto anything with a ring or loop. Here’s where makers use theirs.
Handbag & Purse Strap
Swap a tired store strap for a handmade boho one — instant upgrade to any bag.
Crossbody Strap
At 46” it wears crossbody on most bags. Add length for a longer drop.
Camera Strap
Soft on the neck and sturdy enough for a mirrorless or DSLR — a favorite for photographers.
Yoga Mat Sling
Clip it around a rolled yoga mat for an easy, stylish carry.
Guitar & Ukulele Strap
Boho instrument straps sell for a premium — make your own for a fraction.
Key Lanyard & Wristlet
Make a shorter version as a lanyard or wristlet with a single clasp.
Customize Your Strap
- Length: 46” is crossbody on most bags. Shorten for a shoulder strap or lengthen for an oversized tote — remember square knots use roughly 5× the finished length in cord.
- Width: Add a second column of square knots for a wider, sturdier strap that carries heavier bags.
- Color: Natural cotton is timeless; add a pop with a colored or ombré cord.
- Hardware: Swivel lobster clasps stop twisting; gold or gunmetal hardware changes the whole look.
- Texture: Try a beaded accent or a contrasting gathering-knot color for a designer touch.
What It Costs to Make
A handmade boho bag strap sells for $25–$60; a macramé camera or guitar strap even more. Here’s a realistic breakdown to make your own — if you already have scissors, it’s essentially just cord and clasps.
| Item | Approx. cost | How far it goes |
|---|---|---|
| 3mm cotton cord (roll) | $18–$22 | Makes 5–7 straps |
| Lobster clasps (pack) | $5–$9 | 10+ straps |
| Scissors (one-time) | $8–$15 | Every future project |
| Cost per strap | ~$5 | — |
Pro Tips for a Cleaner Finish
- Consistent square-knot tension. The #1 thing that makes a strap look professional — pull every knot with the same pressure.
- Anchor the clasp. Tape or clip the clasp to your work surface so it stays put while you knot the body.
- Cut long, then trim. Leave a little extra cord and trim at the end — running short mid-strap means starting over.
- Use swivel clasps. They prevent the strap from twisting when it hangs — a small detail that makes it feel store-bought.
- Match the weight to the cord. For heavier bags, use a wider (double-column) strap so it carries comfortably.
- Keep the gathering knot tight. It’s load-bearing near the clasp — wrap it firm and tuck the ends.
Common Mistakes (and How to Fix Them)
| Mistake | Fix |
|---|---|
| Strap comes out too short | Square knots use ~5× the finished length in cord. Always cut the two main cords to at least 255” for a 46” strap. |
| Strap twists when it hangs | Use swivel lobster clasps, and keep your square knots alternating evenly so the body doesn’t spiral. |
| Knots look uneven | Inconsistent tension. Pull each square knot the same amount; undo and re-tie any loose section. |
| Clasp end looks messy | The vertical lark’s head or gathering knot was loose. Re-wrap it snug and trim the tails close, tucking them behind. |
| Strap feels flimsy for a heavy bag | Add a second column of square knots for a wider, stronger strap that carries more weight comfortably. |
What to know before you start
The clasp attachment (Steps 2–3 and 5) is the fiddly part — the long square-knot body in between is genuinely relaxing once you find your rhythm. If your first clasp end looks messy, that’s normal; watch that section of the video again and re-wrap it. And measure your cords generously: the single most common strap mistake is cutting them too short.

Frequently Asked Questions
What can I use a macramé strap for?
Almost anything with a ring or loop. Because it clips on with lobster clasps, one strap can move between a handbag, crossbody purse, camera, yoga mat sling, guitar or ukulele, and more. It’s the most versatile accessory you can knot.
What cord is best for a macramé strap?
A soft-but-sturdy 3mm cotton cord. It’s comfortable on your shoulder and strong enough to carry a bag. A tightly-twisted recycled cotton holds up well under weight. Bamboo cord is another soft option; avoid stiff or scratchy cords.
How much weight can a macramé strap hold?
A single-column 3mm cotton strap comfortably holds an everyday handbag, camera, or rolled yoga mat. For heavier bags, add a second column of square knots to make the strap wider and stronger — more knots means more load capacity.
How long should the cords be, and what strap length does that make?
Cut two main cords at 255” (650 cm) each plus one 20” (50 cm) cord for the gathering knot. That makes a 46” finished strap — crossbody length on most bags. Square knots use roughly 5× the finished length in cord.
What hardware do I need?
Two lobster clasps — one for each end. Swivel-style clasps are best because they stop the strap from twisting as it hangs. You can find them at any craft or hardware store.
Can I make it shorter for a shoulder strap or longer for a tote?
Yes. To shorten, reduce the two main cords by about 5” (13 cm) of cord for every 1” you want off the finished length. To lengthen, add cord the same way. Adjust before you cut.
How do I attach the strap to my bag?
Clip each lobster clasp onto the metal rings or loops on your bag. If your bag doesn’t have rings, you can add small D-rings or use a bag with existing hardware. The clasps make swapping the strap between bags effortless.
What’s the difference between a square knot and a vertical lark’s head?
A square knot uses two working cords tied around a center pair to form a flat, symmetrical knot — it builds the strap body. A vertical lark’s head wraps a single working cord repeatedly around an anchor and is used here to attach the strap cleanly onto the clasp.

Final Thoughts
A macramé strap is one of the highest-value projects you can make — about $5 in cord and clasps turns into a strap worth $25–$60 handmade, and one strap works across your whole life: bag today, camera this weekend, yoga mat on Monday.
