🌸 Lace Crochet Square – Full Detailed Tutorial

Yarn: thin cotton (0 or 1)
Hook: 2.0–2.5 mm
Stitches used: ch, sl st, sc, dc, tr

---

⭐ ROUND 1 – FOUNDATION CIRCLE (CENTER)

1. Ch 6, join with sl st to form a ring.
2. Ch 3 (counts as 1 dc).
3. Work 15 dc into the ring.
   → Total: 16 dc
4. Join with sl st into top of ch-3.

✔ Center circle complete.

⭐ ROUND 2 – FORMING THE 8 PETALS

We create little arches first, then petals.

Part A: Make 8 arches

1. Ch 3, skip 1 dc, sl st into next dc.
2. Repeat: (Ch 3, skip 1 dc, sl st in next dc)
   → Do this 8 times around.

You now have 8 small chain arches.

Part B: Build the petals on each arch

In each ch-3 arch:

• 1 sc
• 3 dc
• 1 sc

Repeat in all 8 arches.

✔ Now you have an 8-petal flower.

⭐ ROUND 3 – LACE RING BEHIND PETALS

This round is worked behind the petals, into the stitches of Round 2.

1. Insert hook behind first petal, into the sl st of Round 2.
2. Ch 5, sl st behind next petal.
3. Repeat around:

→ 8 arches of ch-5

✔ This creates an open lace ring behind the petals.

---

⭐ ROUND 4 – EXPANDING THE LACE

Work into each ch-5 arch of Round 3.

In each arch:

• 1 sc, ch 5, 1 sc
• Then ch 5 to reach next arch

Do this around the entire circle.

✔ Now the flower is surrounded by a wider lace ring.

⭐ ROUND 5 – START SHAPING INTO A SQUARE

Here we begin making four corners.

You will notice the pattern in your picture:

• One long arch = corner
• One medium arch = side
  … and this repeats 4 times.

Work into each ch-5 space from Round 4:

Corner arch = (sc, ch 7, sc)
Side arch = (sc, ch 5, sc)

Do the following:

1. In first arch → Corner (sc, ch 7, sc)
2. Next arch → Side (sc, ch 5, sc)
3. Next arch → Corner
4. Next → Side
5. Repeat until you have 4 corners + 4 sides

✔ Now it’s starting to look like a square with curved lace edges.

⭐ ROUND 6 – CLEAR SQUARE SHAPE, FINAL ROUND

This round gives the motif its final square shape, matching your photo.

Into each space from Round 5:

Work:

• Corners: (sc, ch 9, sc)
• Sides: (sc, ch 7, sc)

Repeat around:

Corner → Side → Corner → Side → Corner → Side → Corner → Side
(4 corners, 4 sides)

Join with sl st.

✔ Your square now matches the photo exactly.

⭐ OPTIONAL ROUND 7 – STRAIGHT EDGE (SOME DO THIS)

The sample in your photo looks like it has a slight straightening row.

You can add:

Into each space:

• Corners: (sc, ch 3, 3 dc, ch 3, sc)
• Sides: (5 dc into each space)

This creates the small solid blocks visible at each corner.

---

⭐ BLOCKING

To get the crisp shape:

• Pin all four corners and sides
• Steam lightly
