Bluebell Lattice Café Curtain Crochet Pattern

This café curtain lets light through a lattice of tall diamonds. Columns of white and cornflower blue alternate across the panel. Every diamond has a spoked wheel at its center, and the diamonds touch tip to tip down each column, so the curtain reads as long vertical chains of lace.

The style is cottage lace: mercerized cotton, open chain mesh, and crisp white scallops along the bottom. Folded tabs in the column colors hang the panel straight from a rod.

This pattern uses US crochet terms. The finished curtain measures 37 in (94.0 cm) wide by 28.5 in (72.4 cm) tall. The tabs add a loop of about 2¼ in (5.7 cm) above that.

You make 36 rectangular motifs in the round, join them into 9 columns of 4, join the columns side by side, and then add a two-round border with scallops and tabs.

Materials

Choose a smooth mercerized cotton in DK weight, about 115 m (126 yd) per 50 g. Cotton gives crisp stitch definition, holds its shape after blocking, and doesn’t fade much in sunlight.

  • Color A, white: 200 g, about 460 m
  • Color B, cornflower blue: 150 g, about 345 m

The quantities include a margin of about 15% for gauge swatching and tension differences.

Tools:
– 4.0 mm (US G-6) crochet hook
– Tapestry needle
– Stitch markers
– Rust-proof pins and a blocking board or foam mats
– Spray bottle
– Measuring tape

Abbreviations (US Terms)

  • ch – chain
  • sl st – slip stitch
  • sc – single crochet
  • hdc – half double crochet
  • dc – double crochet
  • tr – treble crochet
  • dtr – double treble crochet
  • sk – skip
  • sp – space
  • st(s) – stitch(es)
  • rnd – round
  • BLO – back loop only
  • RS / WS – right side / wrong side

Double treble (dtr): Yarn over 3 times, insert hook in the st, yarn over and pull up a loop (5 loops on hook), then [yarn over, pull through 2 loops] 4 times.

Flat slip-stitch seam: Lay two pieces RS up with their edges touching. Insert the hook through the back loop of a st on the right-hand piece, then through the back loop of the matching st on the left-hand piece. Yarn over and pull through everything.

Gauge and Checkpoints

Make one complete motif before you start the others, then block it gently and measure.

  • Edge gauge: 17 sc = 4 in (10.2 cm) across a short side, and 29 sc = 6¾ in (17.1 cm) along a long side
  • After Rnd 2: the wheel is about 2¼ in (5.7 cm) across
  • After Rnd 4: the diamond is about 2¾ in (7.0 cm) wide × 4¼ in (10.8 cm) tall
  • After Rnd 6: the motif is 4 in × 6¾ in (10.2 cm × 17.1 cm)

If the motif is too big, go down to a 3.75 mm hook. If it’s too small, go up to a 4.5 mm hook. A difference of ⅛ in (0.3 cm) per motif adds up to 1⅛ in (2.9 cm) across 9 columns, so it’s worth getting the test motif right.

Motif (make 36)

Each motif is worked in one color from start to finish.

Rnd 1 (RS): Make a magic ring. Ch 3 (counts as dc), work 15 dc in the ring. Join with a sl st to the top of the beg ch-3. (16 dc)

Rnd 2: Ch 5 (counts as dc + ch 2), dc in next dc, ch 2; rep from * 14 more times. Join with a sl st to the 3rd ch of the beg ch-5. (16 dc, 16 ch-2 sps)* These are the wheel spokes.

Rnd 3 (diamond): Sl st into the first ch-2 sp. Ch 4 (counts as tr), work (tr, ch 3, 2 tr) in the same sp for the top point. Then work 3 dc in the next sp, 3 hdc in the next sp, and 3 sc in the next sp. Work (2 sc, ch 2, 2 sc) in the next sp for a side point. Then work 3 sc in the next sp, 3 hdc in the next sp, 3 dc in the next sp, and (2 tr, ch 3, 2 tr) in the next sp for the bottom point. Finish with 3 dc, 3 hdc, and 3 sc in the next 3 sps, (2 sc, ch 2, 2 sc) in the next sp for the second side point, and 3 sc, 3 hdc, and 3 dc in the last 3 sps. Join to the top of the beg ch-4. (52 sts, 2 ch-3 point sps, 2 ch-2 point sps)

The tall trebles at the top and bottom and the short sc at the sides are what stretch the diamond vertically.

Rnd 4 (outline): Ch 1. Sc in the same st and in the next st, then work (sc, ch 3, sc) in the top ch-3 sp. Continue with sc in each st around. Work (sc, ch 2, sc) in each side-point ch-2 sp and (sc, ch 3, sc) in the bottom ch-3 sp. Join to the first sc. (60 sc = 52 worked 1 per existing st + 8 added at the points; 15 sc on each diamond edge, plus 4 point sps)

Rnd 5 (mesh fill): Sl st in the next 2 sc and into the top ch-3 sp. Ch 5 (counts as dtr), ch 2.

Sk 2 sc, dtr in next sc, ch 2, sk 2 sc, (dtr, ch 4, dtr) in next sc for a corner, ch 2, sk 2 sc, tr in next sc, ch 2, sk 2 sc, dc in next sc, ch 2, sk 2 sc, hdc in next sc, ch 2, sc in the side-point ch-2 sp, ch 2, hdc in next sc, ch 2, sk 2 sc, dc in next sc, ch 2, sk 2 sc, tr in next sc, ch 2, sk 2 sc, (dtr, ch 4, dtr) in next sc for a corner, ch 2, sk 2 sc, dtr in next sc, ch 2, sk 2 sc*.

Dtr in the bottom-point ch-3 sp, ch 2. Repeat from * to ** once. Join to the top of the beg ch-5.

(28 sts, 24 ch-2 sps, 4 ch-4 corner sps) Each short side now has 5 sts and 4 ch-2 sps between corner sps. Each long side has 9 sts and 8 ch-2 sps. The stitches step down in height from dtr at the corners to sc at the side points, which turns the diamond into a rectangle.

Rnd 6 (edge): Ch 1, sc in the same st. Work around: sc in each st, 2 sc in each ch-2 sp, and 3 sc in each ch-4 corner sp. Join to the first sc. Fasten off, leaving a 6 in (15.2 cm) tail.

(88 sc: 17 per short side and 29 per long side.) Each side count includes both of its corner sc (the middle sc of each 3-sc group). Check: 28 sts + (24 × 2) + (4 × 3) = 88, and 2 × 17 + 2 × 29 − 4 shared corners = 88.

Make All Pieces

  • Color A (white): 20 motifs
  • Color B (blue): 16 motifs

Weave in the tails on each motif, then lightly steam-block all of them to 4 in × 6¾ in (10.2 cm × 17.1 cm) before joining.

Layout (W = white, B = blue; each motif sits upright, short sides at top and bottom):

W  B  W  B  W  B  W  B  W
W  B  W  B  W  B  W  B  W
W  B  W  B  W  B  W  B  W
W  B  W  B  W  B  W  B  W

Joining

Use Color A and the flat slip-stitch seam for every seam. Joining this way adds no stitches to the panel’s edges.

Step 1 – Columns: Join 4 motifs of the same color short side to short side. Match corner sc to corner sc and work 17 sl sts per seam, so the diamond points meet. Make 9 columns. Each column is 4 in × 27 in (10.2 cm × 68.6 cm), with 4 × 29 = 116 sts along each long edge.

Step 2 – Columns together: Join the columns in layout order along their long edges. Work stitch to stitch for 116 sl sts per seam, matching motif seams to motif seams.

Tension: Keep your sl sts as loose as the sc edge. Pull a seam lengthwise after a few inches. If it puckers, switch to a hook one size larger for the seams.

Checkpoint: After joining 3 columns, the width should be 12 in (30.5 cm). The finished body is 36 in × 27 in (91.4 cm × 68.6 cm). The top and bottom edges each have 9 × 17 = 153 sts, and each side has 116 sts. These counts include the 4 panel corner sts.

Border

The border is worked in Color A and keeps the motif edge gauge of about 4¼ sc per in (2.54 cm).

Border Rnd 1: With RS facing, join yarn in any st on the left side. Sc in each st around, working (sc, ch 2, sc) in each of the 4 panel corner sts. Join.

  • Top and bottom: 153 sc each (151 non-corner sts + 1 sc from each corner)
  • Each side: 116 sc
  • Total: 538 sc (534 worked 1 per existing st + 4 extra at the corners), plus 4 corner ch-2 sps

Border Rnd 2: Sl st to the bottom-left corner ch-2 sp. Ch 1, sc in the sp, and sc in the first bottom st.

Scallops: *sk 3 sts, 9 dc in next st, sk 3 sts, sc in next st; rep from * 18 more times. That’s 19 scallops, and the last sc lands in the last bottom st. Sc in the bottom-right corner sp.

Then sc in each of the 116 side sts, (sc, ch 2, sc) in the top-right corner sp, sc in each of the 153 top sts, (sc, ch 2, sc) in the top-left corner sp, and sc in each of the 116 side sts. Join to the first sc.

Why the math works: The scallops use 1 + (19 × 8) = 153 sts, exactly the bottom count. With 19 scallops across 9 columns, you get about 2 scallops per column. The top keeps 153 sc, which is 17 per column, so the tabs sit evenly.

Tabs (make 9): Number the top sc from right to left. On column k, work into sts 17(k − 1) + 7 through 17(k − 1) + 11, which are the center 5 sts of that column’s 17. Use the column’s color.

  • Row 1: Join the yarn and sc in each of the 5 sts. (5 sc)
  • Rows 2–22: Ch 1, turn, sc in each sc. (5 sc)

Fasten off, leaving a 12 in (30.5 cm) tail. Fold the tab to the WS and sew the last row behind the same 5 sts on Border Rnd 1. Each tab is 1¼ in (3.2 cm) wide and about 4½ in (11.4 cm) long before folding, which makes a loop that fits a rod up to 1 in (2.5 cm) in diameter.

Final Blocking

  1. Weave in all the remaining tails along seams or inside the solid diamond outlines.
  2. Soak the curtain in cool water for 15 minutes, then press out the water in a towel. Don’t wring it.
  3. Lay it flat on the mats with RS up.
  4. Pin the body to 36 in × 27 in (91.4 cm × 68.6 cm), checking that the seams run straight.
  5. Pin each scallop into a round curve, so the full height is 28.5 in (72.4 cm).
  6. Pin the width to 37 in (94.0 cm) at the top, middle, and bottom.
  7. Let it dry completely, then unpin it.

Final Quality-Control Checklist

  • [ ] Every motif measures 4 in × 6¾ in (10.2 cm × 17.1 cm)
  • [ ] All 36 motifs have 17 sts per short side and 29 per long side
  • [ ] The diamond points meet tip to tip in every column
  • [ ] The colors alternate W-B-W-B-W-B-W-B-W
  • [ ] The seams lie flat, with no puckering or gaps
  • [ ] There are 19 even scallops with no extra stitches at the ends
  • [ ] The 9 tabs are centered on the columns and match the column colors
  • [ ] The curtain measures 37 in × 28.5 in (94.0 cm × 72.4 cm)

Troubleshooting

  • Motif is square, not tall: Your trebles at the top and bottom points are too short. Pull up the first loop of each tr and dtr to full height.
  • Corners ruffle: Your Rnd 5 chains are too loose. Make the ch-2 sps snugger.
  • Corners cup inward: The ch-4 corner chains are too tight. Loosen them, or use ch 5 in the corners and keep 3 sc in Rnd 6.
  • Short-side count isn’t 17: Check that you worked 2 sc in every ch-2 sp in Rnd 6 and 3 sc in each corner.
  • Scallops don’t end evenly: Recount the bottom edge. It must be exactly 153 sts between the corner sps.
  • Curtain leans: Re-block it, and pin the seams to a straight line.

Care

Hand wash in cool water with a mild detergent and dry flat. Re-block lightly after washing to restore the scallops and keep the columns straight.

Final Notes

The measurement chain is simple. One motif is 4 in × 6¾ in (10.2 cm × 17.1 cm), with 17 × 29 edge sts. Nine columns of four make a 36 in × 27 in (91.4 cm × 68.6 cm) body, with 153 sts across and 116 down. The border brings the curtain to 37 in × 28.5 in (94.0 cm × 72.4 cm). If your test motif is the right size, every later count and measurement will match.

Happy crocheting!
