The crochet is a delicate lace collar made from connected triangular floral motifs — often called lace insert motifs or collar motifs.
It uses fine cotton thread and a small steel hook (likely 1.25 mm–1.75 mm).
Here’s a step-by-step crochet pattern similar to the one in your image:

🧶 Materials
- Cotton crochet thread size 10
- Steel crochet hook 1.5 mm (or size suitable for your thread)
- Scissors
- Yarn needle
🪡 Stitches Used
- ch = chain
- sl st = slip stitch
- sc = single crochet
- dc = double crochet
- tr = treble crochet
- picot = ch 3, sl st in first ch
🌸 Triangular Floral Motif Pattern
Round 1
- Ch 8, sl st into first ch to form a ring.
- Ch 3 (counts as dc), 23 dc into ring.
- Sl st to top of ch 3. (24 dc total)
Round 2
- Ch 5 (counts as 1 dc + ch 2), skip 1 dc, dc in next dc, ch 2 repeat around.
- Sl st into 3rd ch of beginning ch 5. (12 spaces)
Round 3
- Sl st into first space, ch 3, 2 dc in same space, ch 3, 3 dc in next space, repeat around.
- Sl st into top of ch 3.
Round 4 (Petals)
- Sl st into space between dc groups, ch 3, 6 dc in same space, ch 1, sl st in next space between 3-dc groups.
- Repeat all around. (12 petals)
Round 5 (Lace shaping / triangle)
- Work sc, ch 5, sc between petals to create arches.
- For every third arch, work ch 8 instead of 5 — this forms three triangle corners.
Round 6
- In each ch-5 arch: work (sc, ch 3, dc, ch 3, sc).
- In each corner ch-8 arch: work (sc, ch 5, 5 dc, ch 5, sc). (Triangle shape starts forming)
Round 7 (Final edging)
- Work sc and picots around arches and corners to create the lace edging.
- At corners, add picots evenly spaced between dc stitches.
🧵 Joining Motifs
- Make multiple triangle motifs.
- Join on the last round at the picot points or ch spaces using sl st.
- Arrange in a V shape for a collar.
✨ Optional Finishing
- Block the lace: Pin to shape on a blocking board and steam lightly.
- Weave in ends.
Would you like me to give you a diagram chart (symbol pattern) for this motif too? (It would make it easier to follow.) 🧶📐
