The alternating square knot pattern is the backbone of nearly every macrame wall hanging and plant hanger you have ever seen. It works by tying square knots in a staggered offset grid so each knot in the second row sits between two knots in the first row, with shared cords linking the rows together. The result looks woven and intricate, but once you understand the structure, it is one of the most approachable patterns in macrame. This guide walks through the full technique, including spacing tips for different cord sizes.

What Makes the Alternating Square Knot Pattern Special
A plain row of square knots, repeated straight down, looks like a simple column of bumps. The alternating version looks completely different — it has an interlocked diagonal grid structure that feels almost like fabric. The reason is the cord-sharing between rows.
In Row 1 you tie knots with cords 1-2-3-4, 5-6-7-8, and 9-10-11-12. In Row 2 you skip the first 2 cords and tie knots with cords 3-4-5-6, 7-8-9-10, and so on. Cords 3 and 4, which were the filler cords in one first-row knot, become the working cords in the next row. This handoff is what locks the rows together and creates the woven diagonal lines.
Once you see this structure clearly, the pattern becomes predictable and easy to scale up or down.
What You Will Need
- 4mm cotton macrame cord — a beginner-weight cord that is easy to tension evenly
- A wooden dowel or ring to mount your cords
- A macrame board with T-pins to keep your work flat and aligned
- Scissors and a ruler
For practice, the Macrame Cord for Beginners (4mm 100m Roll) is an ideal starting point — the weight is forgiving and the natural cotton frays beautifully. Use code KNOT10 for 10% off your order.

The Offset Grid Structure Explained
Before starting, it helps to picture the pattern as a grid. Imagine a checkerboard rotated 45 degrees. The dark squares are knots. The light squares are empty spaces. Each knot sits between two knots in the row above and between two knots in the row below.
The diagonal lines you see in the finished pattern are the paths traced by individual cords as they travel through the grid — working in one knot, filling in the next, working again below that. This is why cord tension matters so much. If one cord is pulled tighter than its neighbors, the diagonal line it creates will kink instead of flowing smoothly.
Cord Count Rules
Always use a multiple of 4 cords. Each square knot requires exactly 4 cords. For a practice swatch:
- 8 cords (2 folded lengths): 2 knots per row — good for learning the concept
- 12 cords (3 folded lengths): 3 knots per row — standard small wall hanging
- 16 cords (4 folded lengths): 4 knots per row — medium panel or plant hanger body
- 20 cords (5 folded lengths): 5 knots per row — wider hanging
For the alternating offset, you will always have 2 fewer knots in the offset rows than in the anchor rows, because the edge cords do not have enough partners to form a full knot.
Step-by-Step: How to Tie an Alternating Square Knot Pattern
Step 1: Mount Your Cords
Fold each cord in half and attach it to your dowel using a lark's head knot. Pull each lark's head snug so all cords hang at the same height. For a 12-cord panel, cut 6 lengths at about 2 meters each (the alternating pattern uses cord at a moderate rate, roughly 4x the finished length).
Pin your dowel to your macrame board with T-pins so the piece stays still while you work. Having your work anchored is the single biggest quality-of-life improvement for keeping rows straight.
Step 2: Tie Row 1 of Square Knots
Group your cords from left to right into sets of 4. Tie a square knot with each group. For a 12-cord panel, you will tie 3 knots in Row 1.
Tie each square knot the same way: right working cord over the two fillers, under the left working cord, then left working cord under the two fillers, up through the loop on the right. Pull firmly and evenly. The knot should sit flat and compact.
Step 3: Set Your Row Spacing
This is where many beginners make a critical decision without realizing it. The gap between rows shapes the entire look of the pattern.
- Tight gap (0.5–1cm for 4mm cord): Dense, solid-looking pattern. Good for structural pieces like pot holders or thick wall hangings.
- Medium gap (1–1.5cm for 4mm cord): The classic open-weave look most common in modern boho wall hangings.
- Wide gap (2cm+ for 4mm cord): Very open, lacy look. Good for large decorative panels viewed from a distance.
For 5mm cord, add about 0.5cm to each range. Thicker cord needs more room or the knots crowd each other.
Pick your gap and use a ruler to measure it consistently. Pin a horizontal guide line with T-pins across your board if it helps.
Step 4: Tie Row 2 Offset Square Knots
Here is the core of the alternating technique. Skip the first 2 cords on the left. Then group cords 3-4-5-6 and tie a square knot. Move to cords 7-8-9-10, tie another knot. Continue across. For a 12-cord panel, Row 2 gives you 2 knots positioned between the 3 knots of Row 1.
The 2 cords you skipped on the left (cords 1 and 2) and the 2 leftover on the right are edge cords. They hang free for now. In the next row they rejoin the pattern.
Step 5: Continue Alternating Rows
Row 3 returns to the same grouping as Row 1 — cords 1-2-3-4, 5-6-7-8, 9-10-11-12. Row 4 matches Row 2. Keep alternating. Each row, maintain your consistent spacing gap.
After 4 to 6 rows, the diagonal grid structure will become clearly visible. This is the moment it clicks for most beginners.
Step 6: Check Your Grid Alignment
Step back from your work after every 2 to 3 rows. Look at the diagonal lines running through the pattern. They should flow smoothly from top-left to bottom-right (and top-right to bottom-left), forming clean diamond shapes. If rows look skewed or wonky:
- Re-pin the piece to your board and gently ease it into alignment
- Check that your row spacing is consistent — uneven gaps are the most common culprit
- Make sure you are pulling each square knot with the same tension
Step 7: Finish the Panel
When your panel is the length you want, secure the bottom. A gathering knot pulled tight across all cords gives a clean bottom edge. Alternatively, tie one more row of square knots and then trim and fray the fringe. A macrame fringe comb fluffs the fringe evenly and makes a big difference in the finished look.
Spacing Tips for Different Cord Sizes
| Cord Size | Row Gap | Knot Feel | |---|---|---| | 2–3mm | 0.5–1cm | Delicate, fine-textured | | 4mm | 1–1.5cm | Classic, most versatile | | 5mm | 1.5–2cm | Bold, chunky | | 6mm+ | 2–2.5cm | Very textured, statement piece |
Thicker cord also means each knot takes up more horizontal space, so a 5mm panel with the same number of cords will be noticeably wider than a 4mm panel. Factor this into your cord count when sizing a piece for a specific spot on the wall.

Common Mistakes and How to Fix Them
Rows drifting sideways: You are pulling the offset knots unevenly. Make sure the 2 skipped edge cords on each side hang perfectly vertical between rows. They act as alignment guides.
Knots look different sizes: Tension inconsistency. Practice tying the square knot with a deliberate, repeatable motion. Anchor your filler cords with your non-dominant hand so they stay centered.
The diagonal lines disappear after a few rows: You switched the grouping logic accidentally. In every anchor row, always use the same cord groupings (1-4, 5-8, 9-12). In every offset row, always shift by 2 (3-6, 7-10).
Pattern looks flat and uninteresting: Try a slightly larger row gap to let the diamond shapes breathe. Or add a macrame board with T-pins to your setup — working on a flat surface instead of hanging in the air makes a surprising difference in evenness.
What's Next
Once you are comfortable with flat alternating square knot panels, try applying the same structure to a plant hanger — the pattern wraps around a cylindrical form naturally. Our macrame plant hanger tutorial uses this exact pattern in a three-dimensional piece.
