Seaside Diamond Doorway Curtain Crochet Pattern

This doorway curtain is made of ten long strands of solid diamonds. Small round rings link the diamonds, and the strands hang side by side from a wooden rod. Light comes through the gaps between the diamonds and around each ring, so the curtain gives you shade and privacy without blocking the breeze.

The palette is deep teal and natural cream. The strands alternate colors across the rod, which gives the curtain a calm, coastal stripe. Each diamond is worked in dense single crochet rows and finished with an edging round that makes a neat, rope-like outline.

The pattern uses US crochet terms. The finished curtain is 35 in (88.9 cm) wide and 80 in (203.2 cm) long from the bottom point to the top of the last diamond. The hanging tab adds about 2.25 in (5.7 cm) above that.

Each strand is worked in one continuous piece from the bottom up: a diamond, its edging, a link ring, the next diamond, and so on. You don’t sew any motifs together. The only sewing is closing the hanging tab at the top of each strand.

Finished Size and Construction

  • Finished size: 35 in (88.9 cm) wide x 80 in (203.2 cm) long, plus the hanging tab
  • Skill level: Easy / advanced beginner
  • Terminology: US crochet terms
  • Yarn weight: Worsted (#4), cotton or cotton blend
  • Hook: 5 mm (H-8)
  • Number of pieces: 10 separate strands (5 cream, 5 teal), each with 19 diamonds
  • Layout: 10 strands side by side on one rod, alternating colors and starting with cream
  • Piece size: each diamond is 3.5 in (8.9 cm) wide x 3.5 in (8.9 cm) tall; each link adds 0.75 in (1.9 cm)
  • Size before border: each diamond is 3.25 in (8.3 cm) wide x 3 in (7.6 cm) tall before its edging round
  • Border depth: one round of single crochet on every diamond. It adds 0.25 in (0.6 cm) to the width and about 0.5 in (1.3 cm) to the height.

Materials

Choose a smooth worsted-weight cotton or cotton blend. Cotton holds the diamond shape, doesn’t stretch much under its own weight, and stands up to sun. Avoid fuzzy or very stretchy acrylics, because long strands of those will grow over time.

The amounts below assume a yarn of about 190 m per 100 g.

  • Cream (natural): 600 g, about 1,140 m, for 5 strands
  • Teal: 600 g, about 1,140 m, for 5 strands

One strand uses about 195 m: roughly 10 m for each diamond and its link, plus about 5 m for the tab. The amounts above include a margin of about 15% for gauge differences and swatching.

Tools:

  • 5 mm (H-8) crochet hook
  • Tapestry needle
  • Stitch markers
  • Measuring tape
  • Rust-proof blocking pins and a blocking mat
  • Spray bottle
  • Curtain rod or wooden dowel, at least 38 in (96.5 cm) long and no more than 1.25 in (3.2 cm) across

Abbreviations (US Terms)

  • ch: chain
  • sc: single crochet
  • sl st: slip stitch
  • st(s): stitch(es)
  • sc2tog: single crochet 2 together (a decrease of 1)
  • sc3tog: single crochet 3 together. Insert hook in next st, yarn over, pull up a loop; repeat in the next 2 sts (4 loops on hook); yarn over and pull through all 4 loops. This is a decrease of 2.
  • Row-end: the side edge of a row. Work sc around the outer post of the end st.

The ch 1 at the start of each row does not count as a stitch.

Gauge and Checkpoints

Gauge: 16 sc and 18 rows = 4 in (10.2 cm) in sc rows.

Before you start a full strand, make one test diamond with its edging and link ring. Pin it flat and measure.

  • After Row 7: the widest row is 3.25 in (8.3 cm) across 13 sts.
  • After Row 13: the diamond is about 3 in (7.6 cm) tall, point to point.
  • After the edging: the diamond is 3.5 in (8.9 cm) wide and 3.5 in (8.9 cm) tall.
  • Link ring: about 1 in (2.5 cm) across. After the next diamond is joined, about 0.75 in (1.9 cm) of it shows.

If your diamond is too big, go down half a hook size. If it’s too small, go up half a size. If the width is right but the diamond looks too squat or too tall, change your row height: pull up taller or shorter loops before you finish each sc. Don’t add or remove rows, because the stitch counts set the diamond’s shape.

Pattern: One Strand

Each strand has 19 diamonds and 18 link rings, then a hanging tab. Use one color for the whole strand.

First Diamond

Row 1: Ch 2, 3 sc in 2nd ch from hook. (3 sc) This is the bottom point of the strand.

Row 2: Ch 1, turn, 2 sc in first st, sc in next st, 2 sc in last st. (5 sc)

Rows 3–6: Ch 1, turn, 2 sc in first st, sc in each st to last st, 2 sc in last st.

  • Row 3: 7 sc
  • Row 4: 9 sc
  • Row 5: 11 sc
  • Row 6: 13 sc

Row 7: Ch 1, turn, sc in each st across. (13 sc) This is the widest row, and its two ends become the side points.

Rows 8–12: Ch 1, turn, sc2tog, sc in each st to last 2 sts, sc2tog.

  • Row 8: 11 sc
  • Row 9: 9 sc
  • Row 10: 7 sc
  • Row 11: 5 sc
  • Row 12: 3 sc

Row 13: Ch 1, turn, sc3tog. (1 st) This is the top point.

Rows 1–13 use 97 sts in total. Because each row increases or decreases by 1 st at each edge, both sides slope at the same angle and the diamond stays symmetrical.

Edging round: Do not turn. Work the edging round exactly as written in the Border section below. (32 sc)

Link Ring

  1. After the edging join, sl st in the next sc. This is sc 2, the center of the top corner.
  2. Ch 10, then sl st in the same sc 2 to make a loop.
  3. Work 15 sc over the ch-10 loop. Sl st in the first sc to join. (15 sc)
  4. Sl st in each of the next 5 sc (sc 2–6 of the ring). Keep these slip stitches loose. Your hook is now at the top of the ring.

The sc completely cover the chains, so the ring has the same thick, rope-like look as the diamond edging.

Diamonds 2–19

Row 1: Ch 1, sc in each of the next 3 ring sc (sc 7, 8 and 9). (3 sc) Ring sc 8 is directly opposite the anchor, so the new diamond hangs centered.

Rows 2–13: Work as for the First Diamond. The stitch counts are the same: 5, 7, 9, 11, 13, 13, 11, 9, 7, 5, 3 and 1.

Edging round: Work as in the Border section. Place the bottom-point sc in ring sc 8. (32 sc)

After each of Diamonds 2–18, make a Link Ring. After Diamond 19, go straight to the hanging tab.

Hanging Tab

After the edging join on Diamond 19, your hook is at sc 1.

Row 1: Ch 1, sc in the same st as the join and in each of the next 2 sc. These are sc 1–3, the top corner group. (3 sc)

Rows 2–22: Ch 1, turn, sc in each st across. (3 sc)

The tab is about 4.9 in (12.4 cm) long. Fasten off and leave a 12 in (30.5 cm) tail. Don’t close the tab yet, because it goes around the rod in the Joining section.

Make All Pieces

  • Cream: 5 strands, 19 diamonds each (95 diamonds)
  • Teal: 5 strands, 19 diamonds each (95 diamonds)
  • Total: 10 strands, 190 diamonds, 180 link rings, 10 tabs

Lay the strands out in this order, viewed from the front:

ROD:   C   T   C   T   C   T   C   T   C   T
       1   2   3   4   5   6   7   8   9   10
C = CREAM   T = TEAL

Count your diamonds as you go. A strand that’s one diamond short will hang 4.25 in (10.8 cm) shorter than the others.

Joining

There are two kinds of joins in this curtain: the diamonds are joined into strands, and the strands are joined to the rod.

Diamonds into strands. These joins happen while you crochet. Each link ring is anchored to sc 2, the center of the top corner of the diamond below. The next diamond’s Row 1 grows from ring sc 7–9. Since the anchor and ring sc 8 sit on the same vertical line, every diamond hangs point-to-point with no twist.

Keep your tension on the link rings the same as on the diamonds. If the ch-10 is tight, the 15 sc will cup and the ring will close up. If it’s loose, the ring will flop and the strand will stretch.

Strand length checkpoint:

  • After 5 diamonds: 5 x 3.5 in + 4 x 0.75 in = 20.5 in (52.1 cm)
  • After 10 diamonds: 41.75 in (106.0 cm)
  • After 19 diamonds: 19 x 3.5 in + 18 x 0.75 in = 80 in (203.2 cm)

Check every strand against the first one, and correct any difference early.

Strands onto the rod. Fold each tab over the rod toward the back. Use the tail to whipstitch Row 22 to the back of Row 1, through both loops of all 3 sts, then weave in the end. The folded loop is about 2.25 in (5.7 cm) tall.

Space the strands 3.5 in (8.9 cm) apart, center to center. Ten strands x 3.5 in = 35 in (88.9 cm), so the side points of neighboring diamonds just meet without overlapping. Leave at least 1.5 in (3.8 cm) of rod free at each end for the brackets.

Border: The Diamond Edging Round

This curtain has no outer border around the whole piece. Instead, every diamond gets its own one-round border, and that edging creates the raised outline.

Border gauge: 1 sc per row-end. On a sc row-end that is about 4.5 sc per in (2.5 cm), which matches the row gauge. That’s why the edging lies flat without ruffling or pulling.

Edging round (worked right after Row 13, without turning):

  1. Ch 1. Work 3 sc in the sc3tog of Row 13. These are sc 1–3, and sc 2 is the top point.
  2. First side, going down: sc in the row-ends of Rows 12 to 8 (5 sc), 3 sc in the row-end of Row 7 (side point), then sc in the row-ends of Rows 6 to 1 (6 sc). That’s 14 sc, sc 4–17.
  3. Bottom point: 1 sc into the base of Row 1’s center st. On Diamond 1 that’s the foundation ch; on the other diamonds it’s ring sc 8. This is sc 18.
  4. Second side, going up: sc in the row-ends of Rows 1 to 6 (6 sc), 3 sc in the row-end of Row 7, then sc in the row-ends of Rows 8 to 12 (5 sc). That’s 14 sc, sc 19–32.
  5. Sl st in the first sc to join. (32 sc)

Counts per side: The four corner points are sc 2 (top), sc 10 (side), sc 18 (bottom) and sc 26 (side). Each side runs from one corner to the next, including both corners, so each side has 9 sts.

Why the math works: 4 sides x 9 sts = 36, but each of the 4 corners is counted on two sides. 36 – 4 = 32 sc, which matches the round total. Each corner is exactly 8 sts from the next, so all four edges are the same length and the diamond stays square on its point. The top corner uses 3 sc and the bottom uses 1 sc because the bottom point is already rounded by the 3 sc of Row 1.

Final Blocking

  1. Weave in all ends before blocking.
  2. Lightly mist each strand with water until it’s damp but not wet.
  3. Lay the strand flat on blocking mats in sections, about 5 diamonds at a time.
  4. Pin each diamond at its 4 points to 3.5 in (8.9 cm) wide and 3.5 in (8.9 cm) tall.
  5. Shape each link ring into a round opening about 0.75 in (1.9 cm) long between the diamonds.
  6. Let that section dry completely, then move the next section onto the mats.
  7. Check the full strand: it should measure 80 in (203.2 cm) from the bottom point to the top of Diamond 19.

Final Quality-Control Checklist

  • Every diamond has 32 sc in its edging, with sharp points at sc 2, 10, 18 and 26
  • Every strand has 19 diamonds and 18 link rings
  • Every diamond hangs straight below its ring, with no twist
  • Every strand measures 80 in (203.2 cm) before the tab
  • All tabs are closed to the same 2.25 in (5.7 cm) loop
  • The colors alternate C T C T C T C T C T, starting from the left
  • The strands are spaced 3.5 in (8.9 cm) apart, for a total width of 35 in (88.9 cm)
  • All ends are woven in, with no tails showing on the front

Troubleshooting

The diamond is lopsided. Count Rows 2–6 and 8–12. You need exactly 1 increase or 1 decrease at each edge of every row.

The edging ruffles. You’re probably working 2 sc in some row-ends. Use exactly 1 sc per row-end, except for 3 sc in Row 7.

The edging pulls in. Your hook is too small for the edging. Go up half a size for the edging round only.

The diamonds twist on the strand. Row 1 has to go into ring sc 7–9. Count the 5 sl sts on the ring again.

The strands stretch after hanging. Cotton blends with a lot of drape can grow. Block the strands, hang them for 2 days, then remove diamonds from the bottom if you need to.

The ring closes up. Your ch-10 is tight. Make the chain with a hook half a size larger.

Care

Hand wash the curtain in cool water, roll the strands in a towel, and dry them flat. Reshape the diamonds while they’re damp, and don’t tumble dry.

Final Notes

The measurement chain for this curtain is:

  • Gauge: 16 sc and 18 rows = 4 in (10.2 cm)
  • 13-st Row 7: 3.25 in (8.3 cm) wide
  • Edged diamond: 3.5 in (8.9 cm) wide and tall
  • One diamond plus one link: 4.25 in (10.8 cm)
  • One strand: 19 diamonds and 18 links = 80 in (203.2 cm)
  • Full curtain: 10 strands x 3.5 in = 35 in (88.9 cm) wide

If you check each step against its number, the finished curtain will hang straight and even.

Happy crocheting!
