This curtain is made of hanging strands of open diamonds, crocheted in tight, ribbed single crochet. Each diamond is a firm frame around an open center. The diamonds are linked point to point into long columns, and each strand finishes with a hanging loop at the top and a full tassel at the bottom.
The sample alternates deep forest green and natural cream, which suits winter and the holidays while staying neutral enough to leave up all year. The ribbed texture comes from working in the back loop, so each diamond has neat ridges that follow its outline. Hung in front of a window, the strands make a soft lattice that lets light through.
The pattern uses US crochet terms. One blocked diamond measures 5.75 in (14.6 cm) tall by 4 in (10.2 cm) wide. A finished strand, including the loop and tassel, is about 51.25 in (130.2 cm) long. Eight strands spaced as shown cover about 33.75 in (85.7 cm) of rod.
Construction is simple. Each diamond is worked in the round around a chain ring, with corner increases on four sides, and finished with one border round. The motif starts out as a square and is blocked into a diamond shape. The diamonds are then linked tip to tip into strands, and each strand gets a loop and a tassel.

Materials
Choose a smooth worsted cotton or cotton blend so the ridges stay crisp and the diamonds hold their shape when hung. Acrylic also works, but it can stretch more over time. The amounts below assume about 183 m per 100 g.
- Forest green: 175 g (320 m)
- Natural cream: 175 g (320 m)
The quantities include a margin of about 20% for swatching, tassels, and tension differences.
Tools:
– 5 mm (H-8) crochet hook
– Tapestry needle
– Scissors
– Stiff card, 6.5 in (16.5 cm) tall, for tassels
– Blocking mat and rust-proof pins
– Spray bottle
– Measuring tape
– Wooden curtain rod, at least 36 in (91.4 cm) long
Abbreviations (US Terms)
- ch – chain
- sl st – slip stitch
- sc – single crochet
- sp – space
- st(s) – stitch(es)
- rnd – round
- rep – repeat
Special stitch:
– sc blo (single crochet in back loop only): Insert the hook under the back loop only of the stitch and complete a sc as usual. The unused front loops form the raised ridges.
Gauge and Checkpoints
Gauge: 16 sc × 18 rows = 4 in (10.2 cm) in sc blo.
Make one complete diamond before starting the rest. Check it at each stage:
- After Rnd 1: 6 sc per side, about 1.5 in (3.8 cm) per side on the outer edge
- After Rnd 2: 8 sc per side, about 2 in (5.1 cm)
- After Rnd 3: 10 sc per side, about 2.5 in (6.4 cm)
- After Rnd 4: 12 sc per side, 3 in (7.6 cm)
- After Rnd 5 (border): 14 sc per side, 3.5 in (8.9 cm)
If the motif is too big: Change to a 4.5 mm hook. Also make sure you are not loosening up at the corners.
If the motif is too small: Change to a 5.5 mm hook.
If the motif cups: Your corner chains are too tight. Keep each ch-2 relaxed.
If the motif ruffles: Your corner chains are too loose. Tighten them slightly.
Diamond Motif
Make 28 green and 28 cream.
Foundation: Ch 24 and sl st to the first ch to form a ring, taking care not to twist it. This ring becomes the open center.
Rnd 1: Ch 1. Sc in each of the next 6 ch, ch 2. Rep from * 3 more times. Sl st to the first sc to join.
(24 sc + 4 ch-2 sps; 6 sc per side)
From here on, “stitches per side” counts the sc between two ch-2 corner spaces, including the corner sc on each end.
Rnd 2: Ch 1. Sc blo in each sc to the next ch-2 sp, then work (sc, ch 2, sc) in the ch-2 sp. Rep from * 3 more times, then sc blo in any remaining sc. Sl st to the first sc to join.
(32 sc + 4 ch-2 sps; 8 sc per side)
Rnd 3: Repeat Rnd 2.
(40 sc + 4 ch-2 sps; 10 sc per side)
Rnd 4: Repeat Rnd 2.
(48 sc + 4 ch-2 sps; 12 sc per side)
At this point, measure the motif. It should be 3 in (7.6 cm) per side, flat and square. Leave the yarn attached and continue straight into the border.
Border
Border gauge: 4 sc per inch (per 2.5 cm), the same as the body.
Rnd 5 (border): Ch 1. Working through both loops, sc in each sc to the next ch-2 sp, then work (sc, ch 2, sc) in the ch-2 sp. Rep from * 3 more times, then sc in any remaining sc. Sl st to the first sc to join and fasten off. Weave in the ends.
Count: 48 existing sc worked 1 per stitch + 8 corner sc added = 56 sc + 4 ch-2 sps. That gives 14 sc per side, including the 2 corner sc on each side.
Why the math works: Every round adds exactly 2 sc per side, one at each corner. The 12 sc per side from Rnd 4 plus 2 corner sc gives 14 sc per side. At 4 sts per inch, that is 3.5 in (8.9 cm). Working the border through both loops gives a smooth, firm outer edge that frames the ribbed band.
To shape the diamond, choose two opposite corners as the top and bottom points. On a square with 3.5 in (8.9 cm) sides, the corner-to-corner diagonal is about 4.95 in. Blocking stretches it to 5.75 in (14.6 cm) top to bottom while the width draws in to 4 in (10.2 cm). The geometry checks out: (2.875)² + (2)² ≈ 3.5².
Block each motif before you join (see Final Blocking). Joining is much easier when every diamond already has its finished shape.
Make All Pieces
Totals:
– Green: 28 diamonds and 4 tassels
– Cream: 28 diamonds and 4 tassels
Layout grid (G = green, C = cream; columns are strands, rows are diamonds from the top):
Strand: 1 2 3 4 5 6 7 8
Row 1: G C G C G C G C
Row 2: G C G C G C G C
Row 3: G C G C G C G C
Row 4: G C G C G C G C
Row 5: G C G C G C G C
Row 6: G C G C G C G C
Row 7: G C G C G C G C
Each strand is a single color. The colors alternate across the rod.
Tassels (make 8): Wrap yarn 40 times around the 6.5 in (16.5 cm) card. Slide a 10 in (25.4 cm) tie strand under the wraps at the top and knot it tightly, leaving long tails for attaching. Cut through the wraps at the bottom. Wrap another strand tightly around the tassel 0.75 in (1.9 cm) below the top, about 8 times, then knot it and bury the ends inside. Trim the tassel to 6 in (15.2 cm).
Joining
Each strand is built by linking 7 diamonds of the same color point to point, from top to bottom.
Link method:
1. Lay diamond A above diamond B, with A’s bottom point touching B’s top point.
2. Join yarn with a sl st in the bottom ch-2 sp of diamond A.
3. Ch 2, then sl st in the top ch-2 sp of diamond B.
4. Sl st in each of the 2 ch back up toward A, then sl st in A’s ch-2 sp.
5. Fasten off and weave in the ends.
Stitch logic: The link only uses the corner chain spaces. The side stitch counts do not change, and no stitches are added along the sides. Each finished link is 0.5 in (1.3 cm) long.
Tension advice: Work the chains at the same tension as the motif. If the links are tight, the strand will kink. If they are loose, the diamonds will twist and turn sideways on the rod.
Hanging loop: Join yarn in the top ch-2 sp of the first diamond. Ch 2 for the stem, then ch 12 and sl st into the first of those 12 ch to close the loop. Sl st in each of the 2 stem ch, sl st in the ch-2 sp, and fasten off. The loop and stem together measure about 2 in (5.1 cm).
Tassel: Thread the tassel’s tie tails through the bottom ch-2 sp of the last diamond. Knot them securely and bury the ends inside the tassel head.
Size checkpoint for each strand:
– 7 diamonds × 5.75 in = 40.25 in
– 6 links × 0.5 in = 3 in
– Loop: 2 in
– Tassel: 6 in
– Total: 51.25 in (130.2 cm)
Lay each finished strand flat and compare it with the others. All 8 strands should be within 0.5 in (1.3 cm) of each other.
Hanging the curtain: Slide the loops onto the rod in the order shown in the grid, spacing them 4.25 in (10.8 cm) center to center. This leaves a small gap between the widest points of neighboring diamonds. The 8 strands span about 33.75 in (85.7 cm).
Final Blocking
- Soak each diamond in cool water for 10 minutes, then gently press the water out with a towel. Do not wring.
- Pin the motif on a blocking mat, top point up.
- Pin the top and bottom points 5.75 in (14.6 cm) apart.
- Pin the two side points 4 in (10.2 cm) apart.
- Pin each side straight, keeping all four sides at 3.5 in (8.9 cm).
- Shape the center opening into a matching smaller diamond with a few pins along the inner edge.
- Let it dry completely, about 24 hours.
- After joining, hang each strand and lightly mist it so it relaxes straight. Comb the tassels and steam them gently if needed.
Final Quality-Control Checklist
- Each diamond has 56 sc and 4 ch-2 sps in the border, with 14 sc per side.
- All ridges show on the same side of every motif.
- Each diamond is 5.75 in (14.6 cm) × 4 in (10.2 cm) after blocking.
- Every link is 0.5 in (1.3 cm) and lies flat.
- Each strand has 7 diamonds, a 2 in (5.1 cm) loop, and a 6 in (15.2 cm) tassel.
- All strands are within 0.5 in (1.3 cm) of each other in length.
- All ends are woven in securely.
- The colors alternate G, C, G, C across the rod.
Troubleshooting
Corners are rounded instead of pointed: Make sure every corner gets (sc, ch 2, sc) worked into the space itself, not into the neighboring stitch. Pin the points firmly when blocking.
Center opening looks uneven: The foundation chain was probably tight. Remake the motif with a looser chain or go up one hook size for the foundation only.
Diamond twists on the strand: Check that every motif has its ridges facing forward before linking. Remake any link that pulls to one side.
Wrong stitch count on one side: You probably skipped or doubled a stitch next to a corner. Count each side between corner spaces and frog back to the round where the count first went wrong.
Tassel looks thin: Increase the wraps to 50, or use a slightly thicker yarn just for the tassels.
Strands hang at different lengths: Re-block the shorter strand and stretch it gently while damp, or redo the hanging loop with 1 extra stem chain.
Care
Hand wash in cool water with mild soap, press out the water in a towel, and dry flat with the diamonds reshaped. Comb the tassels while damp and rehang once fully dry.
Final Notes
The measurements build in a simple chain. The gauge of 4 sc per inch gives 14 sc per side after the border, which is 3.5 in (8.9 cm). Blocking turns that square into a diamond of 5.75 in (14.6 cm) × 4 in (10.2 cm). Seven diamonds plus six 0.5 in (1.3 cm) links, a 2 in (5.1 cm) loop, and a 6 in (15.2 cm) tassel make a strand of 51.25 in (130.2 cm). Eight strands spaced 4.25 in (10.8 cm) apart cover 33.75 in (85.7 cm) of rod. If you check your gauge on the first motif, every later measurement will follow.
Happy crocheting!
