The Lilac Fanlight curtain panel is a tall, airy piece of fan-and-diamond lace. Each fan opens upward from a small chain ring. Diagonal chain lines frame the fans into diamonds, and the bottom edge ends in a row of soft points. When light comes through a window, the lace throws a pattern onto the floor.
The panel uses one color, a gentle lavender, so the stitch pattern does all the decorative work. The style is vintage pineapple lace with a clean, modern outline. The pattern uses US crochet terms throughout.
Each finished panel measures 21 in x 61.5 in (53.3 cm x 156.2 cm), including the pointed hem and side border. The photo shows a matching pair, so this pattern makes two identical panels. They are worked separately and are never joined.
You work each panel in one piece from the bottom up, starting from a foundation chain. After the lace body is done, you add a pointed edging along the foundation edge and a two-row border up the sides and across the top.
Finished Size and Construction
- Finished panel size: 21 in x 61.5 in (53.3 cm x 156.2 cm)
- Skill level: Intermediate
- Terminology: US
- Yarn weight: Worsted (#4), cotton or cotton blend
- Hook: 5.5 mm (I-9)
- Number of pieces: 2 identical panels, each worked in one piece, not joined
- Layout: Panels hang side by side on a rod
- Lace body per panel: 20 in x 58.5 in (50.8 cm x 148.6 cm)

Materials
Use a smooth, mercerized or combed cotton. Cotton holds the open lace crisp, blocks well, and doesn’t stretch out much under its own weight. Acrylic tends to sag over a long drop.
- Lavender: 600 g / 1,140 m (1,247 yd) per panel; 1,200 g / 2,280 m (2,493 yd) for the pair
These quantities include about a 10% margin for swatching and blocking.
Tools:
– 5.5 mm (I-9) crochet hook, plus a 6.0 mm (J-10) hook for the foundation chain
– Stitch markers
– Tapestry needle
– Rust-proof pins and a large blocking surface
– Spray bottle
– 8 curtain clip rings per panel
Abbreviations (US Terms)
- ch – chain
- sl st – slip stitch
- sc – single crochet
- dc – double crochet
- tr – treble crochet
- rev sc – reverse single crochet (crab stitch)
- sk – skip
- sp(s) – space(s)
- st(s) – stitch(es)

Special terms:
– Ring: (sc, ch 3, sc) in the same stitch. The ch-3 sp becomes the base of a fan.
– Fan: 9 dc worked into a ring.
– Half fan: 5 dc worked into an edge ring.
– Fan top: 1 sc in each ch-2 sp of a fan, with ch 3 between. Each full fan top has 8 sc and 7 inner ch-3 sps, plus 1 flanking ch-3 sp on each side.
– Rev sc: Work single crochet from left to right (right-handers) without turning.
Gauge and Checkpoints
Gauge (blocked): One 12-st repeat = 5 in (12.7 cm) wide. Rows 1–5 = 3 in (7.6 cm). Each 8-row repeat (Rows 6–13) = 5 in (12.7 cm).
Border gauge: 4 sc = 1 in (2.5 cm).
Test swatch: Before starting a full panel, make one test piece. Ch 25 and work Rows 1–13 with 2 repeats across instead of 4. Wet block it. It should measure 10 in x 8 in (25.4 cm x 20.3 cm).
- Swatch too big: Go down to a 5.0 mm hook.
- Swatch too small: Go up to a 6.0 mm hook.
Lace relaxes when it’s off the pins, so always measure blocked fabric.
Checkpoints on the panel (blocked or gently stretched):
– After Row 5: 20 in (50.8 cm) wide, 3 in (7.6 cm) tall
– After Row 13: 8 in (20.3 cm) tall
– After Row 53: 33 in (83.8 cm) tall
– After Row 93: 58 in (147.3 cm) tall
– After Row 94: 58.5 in (148.6 cm) tall

Make the Second Panel
Repeat everything above for a second, identical panel, using 600 g / 1,140 m (1,247 yd) of lavender. The panels are not joined. Each one hangs independently from its own clip rings:
[ Panel A ] (window) [ Panel B ]
21 in 21 in
53.3 cm 53.3 cm
Border
The border runs up the right side, across the top, and down the left side. The bottom edge is already finished by the points. Border gauge is 4 sc = 1 in (2.5 cm).
Border Row 1 (RS): With RS facing, join yarn at the lower right corner. Work 236 sc evenly up the side:
– 1 sc in the end of each Point Row (2 sc)
– 12 sc across Rows 1–5
– 20 sc across each 8-row repeat (220 sc)
– 2 sc in the end of Row 94
Then work across the top: 3 sc in the first st of Row 94, 1 sc in each of the next 78 sts, and 3 sc in the last st. Work 236 sc down the left side in reverse order of the right side.
(556 sc)
The middle sc of each 3-sc group is a corner stitch. Counted corner to corner, the top has 82 sts, including both corner sts. Each side has 238 sts: 236 + 1 + the corner st.
Border Row 2 (RS, do not turn): Ch 1, rev sc in each sc back along the whole edge. Fasten off.
(556 rev sc: 238 per side, 82 across the top, with the corners shared)
Why the math works:
– Top: 80 sc ÷ 4 = 20 in (50.8 cm). That matches the 4 lace repeats at 5 in (12.7 cm) each.
– Sides: 236 sc ÷ 4 = 59 in (149.9 cm). That’s the 58.5 in (148.6 cm) body plus 0.5 in (1.3 cm) of point rows at the corner.
– No stitches are added along the edges, so the border lies flat without ruffling or pulling.
Final Blocking
- Weave in all ends along solid dc or sc lines.
- Soak the panel in cool water for 15 minutes. Press out the water without wringing, then roll it in towels.
- Lay it flat and pin the top edge straight at 21 in (53.3 cm) wide.
- Pin both sides straight down to 59.5 in (151.1 cm) at the corners: 59 in of side border plus 0.5 in of top border.
- Pin each point tip 2.5 in (6.4 cm) below the valleys. The finished length should be 61.5 in (156.2 cm).
- Open each ring and fan with your fingers, and line up the diamonds vertically.
- Let it dry completely before unpinning.
Final Quality-Control Checklist
- 4 points along the bottom, each centered under a fan
- Fans stagger in half-drop bands, with half fans and half pineapples alternating at the edges
- Top edge has 80 sc and lies straight
- Each side has 236 border sc and no ripples
- Panel is 21 in x 61.5 in (53.3 cm x 156.2 cm) blocked
- Both panels match within 0.5 in (1.3 cm)
Troubleshooting
- The bottom edge puckers: The foundation chain is too tight. Restart with a larger hook for the chain.
- Fans cup or ruffle: Check that each fan has exactly 9 dc. Tighten the ch-2 sps in the widest fan row.
- The edges are shorter than the center: Loosen the edge chains. Blocking also evens out small differences.
- Diamonds lean: Recount the pineapple loops. Each pineapple should go from 4 loops, to 1 loop, to a single tip sc.
- The border waves: Remove it and rework with fewer sc, keeping 20 per 8-row repeat.
Care
Hand wash in cool water with a mild detergent. Then dry flat and re-pin as needed. Keep the panels out of strong direct sun for long periods to protect the color.
Final Notes
The measurement chain is simple:
– One 12-st repeat is 5 in (12.7 cm), so 4 repeats make 20 in (50.8 cm).
– Rows 1–5 are 3 in (7.6 cm), and 11 eight-row repeats add 55 in (139.7 cm). With the top row, the body is 58.5 in (148.6 cm).
– The points add 2.5 in (6.4 cm), and the border adds 0.5 in (1.3 cm) on the sides and top.
– That gives 21 in x 61.5 in (53.3 cm x 156.2 cm) per panel.
Check your swatch, measure at every checkpoint, and both panels will match.
Happy crocheting!
