What Is a Macramé Diamond Coaster?
A macramé diamond coaster is a square drink coaster (approximately 3.5–4.5" wide) featuring a single bold diamond shape made from S-shaped square knots, framed by clean double half hitch borders and soft fringed top and bottom edges. The diamond pattern reads as both vintage and modern — boho on a coffee table, but tidy enough for a polished tabletop setting.
What makes this coaster so popular:
- Beginner-friendly. It uses just three macramé knots, all of which are foundational.
- Fast. Once you've made one, each subsequent coaster takes about 30 minutes. A set of 4 fits inside one Sunday afternoon.
- Budget-friendly. Total cost is under $2 per coaster in materials. One spool of 3 mm cord makes 15+ coasters.
- Giftable. Sets of 4 or 6 matching coasters are go-to housewarming, wedding, and hostess gifts.
- Endlessly customizable. Swap colors, scale up or down, or vary the fringe length to match any decor.
What Is the S-Shaped Square Knot?
The S-shaped square knot (also called an extended square knot or 1.5 square knot) is the knot that makes this coaster's diamond pattern so visually distinctive. It's a standard square knot with one extra half-knot tied in the opposite direction at the end.
That extra half-knot:
- Adds a subtle "twist" to each knot
- Creates a small "S" silhouette when you look at the knot edge-on
- Gives the entire diamond row a textured, almost woven appearance
It takes the same time as a regular square knot — just one extra motion at the end. If you can tie a square knot, you can tie an S-shaped square knot.

Cord Lengths to Cut
| Quantity | Length (cm) | Length (inches) | Purpose |
|---|---|---|---|
| 10 cords | 110 cm | 43" | Mounted on dowel with lark's head knots — gives 20 working cords |
How to Make a Macramé Diamond Coaster (Step-by-Step)
Follow the 8 steps below. Each has a photo and clear bullet instructions. If you get stuck on any step, the video at the top of the page walks through every step in real time.
Step 1: Attach 10 Cords with Lark's Head Knots
- Fold each 110 cm cord in half and attach it to the dowel using a lark's head knot.
- You should have ten evenly spaced lark's head knots across the dowel — 20 working ends in total.
Step 2: Start the First S-Shaped Square Knot in the Center
- Measure about 1"–1.5" down from the top and use the middle four cords to tie a square knot. Then add one more half knot in the opposite direction to form the S-shaped square knot.
- That little extra half knot produces the subtle S texture that makes this diamond coaster so distinctive.
Step 3: Create the Upside-Down V with Alternating S-Shaped Square Knots
- Working outward from the center, make alternating S-shaped square knots diagonally to the left and right.
- Mirror both sides so the pattern forms an upside-down V. Continue the diagonal rows until you reach the outer cords.
Step 4: Fill the Middle and Build the Diamond
- After the V shape is established, fill in the center section by tying S-shaped square knots in vertical rows.
- Continue downward, then reverse direction and make rows with one fewer knot each time (4, 3, 2, 1) to close the diamond.
Step 5: Trim and Prepare Anchor Cords for Double Half Hitch Rows
- Identify the two longest fringe cords (one on the left and one on the right are typical). Leave ~3" of fringe and cut the rest off the very ends.
- Use one of the trimmed strands to form a V-shaped anchor at the bottom of the diamond for double half hitch knots.
Step 6: Anchor the Diamond with Double Half Hitch Knots
- With the anchor cord in place, use vertical cords to tie double half hitch knots along the anchor, moving across to the right, then repeating on the left.
- This neatly secures the bottom edge of the diamond coaster and creates a clean V finish.
Step 7: Remove the Dowel and Convert the Top Loops to Fringe
- Cut the loops at the top to free the macramé from the dowel, turning those loops into fringe.
- Use the second trimmed cord (from Step 5) as an anchor to repeat the DHH row on the top side, then close the piece by tying the final double half hitch knot that connects both anchor cords.
Step 8: Finish by Trimming and Combing the Fringe
- Trim any uneven ends and, if you like, comb the fringe for a fluffy finish. You can also leave it flat, depending on your aesthetic. Your diamond coaster is now ready to use.
How Long Does a Macramé Diamond Coaster Take to Make?
A macramé diamond coaster takes 30–45 minutes per coaster for confident beginners. First attempts may take closer to 60–90 minutes; once you've made one or two, you can complete one in 25–30 minutes flat. A set of 4 matching coasters takes about 2–3 hours total.
| Phase | Time (first try) | Time (with practice) |
|---|---|---|
| Phase 1 — Mount cords (Step 1) | ~10 min | ~3 min |
| Phase 2 — Build the diamond (Steps 2–4) | ~40 min | ~15 min |
| Phase 3 — Anchor edges (Steps 5–7) | ~15 min | ~8 min |
| Phase 4 — Trim & comb fringe (Step 8) | ~5 min | ~3 min |
| Total per coaster | ~70 min | ~30 min |
| Set of 4 (with practice) | ~3 hours | ~2 hours |
How Much Does a Macramé Diamond Coaster Cost to Make?
Total materials cost is approximately $1.50 to $3 per coaster. Buying cord in bulk drops the cost significantly — a single 100 m spool of 3 mm cord makes roughly 18 to 20 diamond coasters.
| Material | Used per coaster | Bulk pack price | Cost per coaster |
|---|---|---|---|
| 3 mm single-strand cotton cord | ~5.5 m (10 × 110 cm) | 100 m spool | ~$1.50–2.00 |
| 12" wooden dowel | Reused for every coaster | 5-pack | $0 (reusable) |
| Total per coaster | ~$1.50–2.00 |
Pro Tips for a Clean Diamond Pattern
- Space the lark's heads evenly. Use a ruler to mark exact spacing on the dowel before attaching cords — uneven spacing in Step 1 shows up everywhere later.
- Keep the diamond centered. Find the exact middle 4 cords (cords #9, #10, #11, #12 out of 20) for the center knot. Off-center starts make the diamond look lopsided.
- Don't over-tighten the S-knots. Each S-knot should sit flat but not strained. Too tight = the diamond curls. Too loose = the diamond looks sloppy.
- Mirror the V symmetrically. Tie the left side first, then count knots before mirroring on the right. If the right wing has 5 knots, the left wing must have 5 too.
- Count the closing rows. The decreasing rows at the bottom should follow the pattern 4 → 3 → 2 → 1 knots. Skipping a row makes the bottom blunt instead of pointed.
- Steam the fringe before trimming. A 5-second hover with a fabric steamer relaxes any kinks and makes the fringe sit flat for an even cut.
- Use the metal comb gently. Comb downward in short strokes. Aggressive combing frays the cord.
Common Mistakes & How to Fix Them
| Mistake | What happens | How to fix it |
|---|---|---|
| Tied a regular square knot instead of S-knot | No subtle "S" texture; pattern looks plain | Add one extra half-knot in the opposite direction at the end of each square knot |
| Lark's heads unevenly spaced | Diamond is lopsided from the start | Mark exact spacing on the dowel with pencil before attaching cords; redo if very uneven |
| Started off-center | Diamond drifts to one side | Use cords #9–#12 (out of 20) for the center knot; recount before tying |
| Mismatched wing knot counts | Left and right sides of the V have different lengths | Count knots on each wing as you go; the left and right must mirror exactly |
| Skipped a closing row | Bottom of diamond is blunt or asymmetric | Follow the exact 4 → 3 → 2 → 1 decreasing pattern |
| Trimmed anchor cord too short in Step 5 | Can't complete the DHH row | Leave at least 3" of anchor cord; you can trim more later |
| Cut the dowel loops too low in Step 7 | Top fringe is too short | Cut as high as possible just above the dowel; you can always trim more, but you can't add length back |

Macramé Diamond Coaster FAQ
What cord thickness is best for the diamond coaster?
3 mm single-strand cotton cord is ideal — it's sturdy, gives texture, and knots cleanly. You can use slightly thinner (2 mm) or thicker (4 mm) cord, but adjust the cord lengths and knot spacing accordingly. Avoid hollow braided cord for this pattern; the S-knots don't show as crisply.
How long should each cord be?
Cut ten cords at approximately 110 cm (43") each. This length provides enough material for the knot rows and fringe trimming. If you scale the coaster larger, increase the length proportionally — use the macramé Golden Ratio (cord length = 5× finished size, doubled because the cord folds in half for the lark's head).
How many cords do I need for a macramé diamond coaster?
You need 10 cords at 110 cm each. After folding each in half for the lark's head knots, you'll have 20 working cords across the dowel — the right amount for the diamond pattern's structure.
Can I make a set of diamond coasters as gifts?
Absolutely. The diamond coaster is quick to make — four coasters can be completed in 2 to 3 hours total — and they make thoughtful housewarming, wedding, and hostess gifts. Sets of 4, 6, or 8 in matching or coordinating colors are the most popular gift configurations.
Which knots define the macramé diamond coaster pattern?
Three foundational macramé knots: the lark's head knot mounts the cords to the dowel, the S-shaped square knot (a square knot plus an extra half-knot) forms the diamond texture, and double half hitch knots tidy and anchor the bottom and top edges.
What is the S-shaped square knot?
The S-shaped square knot (also called an extended square knot or 1.5 square knot) is a standard square knot with one extra half-knot tied in the opposite direction at the end. That extra motion adds a subtle "S" texture to each knot, which gives the diamond pattern its distinctive woven appearance.
How long does it take to make a macramé diamond coaster?
30 to 45 minutes per coaster for confident beginners; under 30 minutes once you've made a few. A set of 4 coasters takes about 2 to 3 hours total.
How much does a macramé diamond coaster cost to make?
Approximately $1.50 to $2 per coaster in materials. One 100-meter spool of 3 mm cotton cord makes about 18 to 20 diamond coasters. A set of 4 costs you roughly $6 to $8 in materials.
Can I sell macramé diamond coasters I make from this tutorial?
Yes. The finished coasters you make are yours to sell. You may not copy or republish the tutorial itself, but products you make from your knowledge are completely yours. Diamond coasters typically sell for $8 to $15 each in person and $25 to $45 as a 4-pack set on Etsy.
Do I need to know macramé before starting this project?
It helps to know three basic macramé knots first: the lark's head, the square knot, and the double half hitch. If you're brand new to macramé, start with our complete beginner's guide first to learn all 4 basic knots in about 30 minutes.
What's the difference between the diamond coaster and the bear coaster?
The macramé bear coaster is round and shaped like a bear with tiny ears and a clean no-fringe edge; this diamond coaster is square with fringed top and bottom and a single bold diamond pattern. The bear coaster uses braided cord and only double half hitch knots; the diamond coaster uses single-strand cord and three different knots.
Can I make the diamond coaster bigger to use as a placemat?
Yes — scale up by using 25 cords at 200 cm each, mounted on a 24" dowel. The finished placemat will measure approximately 12" × 12". You may need to add intermediate "fill rows" of S-knots between the V borders depending on the exact ratio.
