ch – chain
sl st – slip stitch
sc – single crochet
hdc – half double crochet
dc – double crochet
tr – treble crochet
st – stitch
sk – skip
rep – repeat

Treble Crochet (tr):
Yarn over twice, insert hook, yarn over, pull through, yarn over, pull through 2 loops (three times total).

🪄 Step-by-Step Instructions

🔘 Center Circle

Start: Make a magic ring or ch 4, sl st into first ch to form a ring.
Round 1: Ch 3 (counts as dc), work 11 dc into the ring. Sl st to join. (Total: 12 dc)

🌙 Half-Circle Rows (Refer to color changes between rows for added effect)

2:

Ch 3 (counts as 1 dc),
Ch 2, dc in next stitch, ch 2 – repeat from * to end of row.
You’ll create a dc separated by ch-2 spaces across the row.

3:

Ch 3 (counts as dc),
Ch 4, skip 2 sts, dc in next st, ch 4 – repeat across.
This creates wider mesh-like spacing.

4:

Ch 3 (counts as dc),
Work 1 dc in next 4 stitches,
Ch 1, 4 dc in next 4 sts – repeat this cluster and ch-1 spacing across.
End with 5 dc (for symmetry).

5:

Ch 3 (counts as dc),
Dc in every stitch and space across to fill the row solidly.
No chaining or skipping here.

6:

Ch 3 (counts as dc), dc in same stitch (2 dc total in 1 st),
Ch 1, skip 1 stitch, 2 dc in next 2 stitches,
Ch 1, skip 1 st, (dc, ch 1, dc) in same stitch,
Repeat pattern till end.

This row adds gentle fans and lacy spacing.

7:

Ch 3, dc in same st,
Ch 2, skip 1 st, work 2 dc together (dc2tog) over next 2 sts (a decrease)
Ch 2, skip 1, work 4 dc in the same st,
Ch 2, skip 1, dc2tog again…
Continue repeating the sequence to build the rhythm of fans and valleys.

8:

Dc in next stitch
Ch 3, skip 2 stitches
Dc in next stitch
Ch 3, 1 dc in each of the next 4 stitches
Ch 3, skip 3 stitches
Dc in next stitch

🔁 Repeat this pattern until the end of the row.
This creates beautiful arched spacing and blocks across the fan.

9:

Ch 3 (counts as dc)
Ch 4, skip 2 stitches
Sc in next stitch
Ch 4, skip 2 stitches
Dc, Ch 1, Dc in the same stitch (creates a V-stitch)
Ch 4, skip 2 stitches
Sc in next stitch
Ch 4, skip 2 stitches
Dc in next 2 stitches

🔁 Repeat this sequence across the row.

This creates a nice open lace structure with alternating V-stitches, single crochets, and 2-dc clusters with ch-4 arches in between—just as shown in the chart!

10–15:

Follow the visual stitch chart for detailed lace arches, scallops, and edge picots. These rows consist mostly of:

Alternating V-stitches
Ch 4–6 arches
Scalloped edging with picots
Occasional treble/double treble clusters

A: Absolutely. Continue the pattern symmetrically to complete the circle.

Q: Is it beginner-friendly?
A: Intermediate crocheters will enjoy it best, but adventurous beginners can try with guidance from the diagram.
