This purple petal lace crochet blanket has such a soft, elegant look. Each motif is made as a four-petal flower with rich purple centers and a thick white crochet outline, then the motifs are joined together to create a light openwork fabric.

The finished design looks delicate but structured, with repeated flower shapes forming a pretty lace blanket, table runner, shawl panel, or decorative throw. It is a beautiful crochet motif project for anyone who loves floral texture, contrast colors, and joined crochet squares without the traditional granny square look.

Description

This crochet project is made from repeated four-petal flower motifs. Each motif has purple teardrop-style petals that meet in the center, with a soft white border outlining every petal. When the motifs are joined, the white outlines create a clean lattice effect between the flowers. The finished fabric has small open spaces between motifs, giving it a lace-style look while still feeling soft and cozy. The sample style uses purple and white, but the motif can be made in any two-color combination.

Step-by-Step Instructions

Four-Petal Flower Motif

Make as many motifs as needed.

Use purple for the petal center and white for the outline.

Round 1: Purple Center

With purple yarn, make a MR.

Ch 1.

Work 8 sc into the ring.

Pull the ring closed.

Join with sl st to the first sc.

You should have 8 sc.

Round 2: Purple Petal Foundations

Ch 1.

Sl st in the first st.

Ch 8.

Working back down the chain:

Sc in the 2nd ch from hook.
Hdc in next ch.
Dc in next 2 ch.
Tr in next 2 ch.
Dc in last ch.

Sl st into the next st of the center ring.

This makes the first purple petal.

Repeat 3 more times:

Sl st in next st, ch 8, sc in 2nd ch from hook, hdc in next ch, dc in next 2 ch, tr in next 2 ch, dc in last ch, sl st into next st of center ring.

You should now have 4 purple petals arranged like a flower.

Fasten off purple.

Round 3: White Petal Outline

Join white yarn at the base of any purple petal.

Ch 1.

Work around the first petal as follows:

Sc along the first side of the petal.
Work 2 sc at the top point of the petal.
Sc down the other side of the petal.
Sl st into the center space between petals.

Repeat around each of the 4 petals.

As you outline the petals, the white yarn should frame the purple petal shape clearly.

Join with sl st to the first sc.

Do not fasten off yet.

Round 4: White Raised Edge

Ch 1.

Sc in each white outline stitch around the first petal.

At the top of each petal, work:

Sc, ch 2, sc.

This creates a small joining point at each petal tip.

In the dip between petals, work sl st or sc to keep the center space neat.

Repeat around all 4 petals.

Join with sl st to the first sc.

Fasten off, leaving a tail if you plan to sew the motifs together.

Your motif should now have:

• 4 purple teardrop petals
• a small center opening
• a thick white outline
• 4 petal-tip points for joining

Make More Motifs

Make multiple motifs in the same way.

For the look shown in the image, make all motifs with purple petals and white outlines.

You can also vary the purple shades slightly for a softer gradient effect.

Join-As-You-Go Method

This method creates the connected lace fabric while you crochet the final white round.

Make the first motif completely.

For the second motif, work Rounds 1–3 as usual.

On Round 4, when you reach the petal tip that should connect to the first motif:

Work sc at the petal tip.
Ch 1.
Sl st into the matching ch-2 petal tip of the finished motif.
Ch 1.
Sc back into the same petal tip of the current motif.

Continue working around the motif.

Join each motif at one or two petal tips where it touches the next flower.

For a stronger fabric, join at both petal tips that touch neighboring motifs.

Sewn Join Method

If you prefer to make all motifs first, use this method.

Lay all motifs flat in your chosen layout.

Place the motifs so the white petal tips touch.

Thread a yarn needle with white yarn.

Sew the petal tips together using small neat stitches.

Join each motif to the motifs beside it and above it.

Keep the sewing on the back side so the front looks clean.

Do not pull too tightly, or the lace fabric may pucker.

Motif Layout

Arrange the motifs in straight rows.

The flowers should sit close together, with small diamond-shaped open spaces between them.

A simple layout:

Row 1: 8 motifs
Row 2: 8 motifs
Row 3: 8 motifs
Continue until the blanket reaches your desired length.

For a more lace-like effect, slightly stagger every other row so the petals nest between each other.

Fill Small Gaps

After joining the motifs, you may see small open spaces between flowers.

You can leave them open for a delicate lace look.

For a slightly firmer blanket, add small white connector stitches:

Join white yarn at one petal tip.

Ch 3.

Sl st into the nearest petal tip of the next motif.

Ch 3.

Sl st into the next nearby petal tip.

Fasten off and weave in ends.

Keep these connectors loose so the blanket stays flexible.

Border Round 1: White Foundation Border

Join white yarn at any outer petal tip.

Ch 1.

Sc evenly around the outside edge of the blanket.

Work 2 sc into each outer petal tip.

Work 1 sc or sl st into each dip between motifs.

At corners, work 3 sc to help the corner turn neatly.

Join with sl st to the first sc.

Border Round 2: Clean White Edge

Ch 1.

Sc in each st around.

At each corner, work 3 sc in the middle corner stitch.

Join with sl st.

Optional Scalloped Border

For a softer decorative edge:

Ch 1.

Skip 1 st.

Work 5 dc in next st.

Skip 1 st.

Sl st in next st.

Repeat around the blanket.

Adjust spacing at corners and motif curves so the border sits flat.

Fasten off and weave in all ends.

Finishing

Weave in all yarn tails.

Lay the blanket flat.

Gently shape the flower motifs with your fingers.

Pin the edges and corners if needed.

Lightly steam or damp block the blanket so the white outlines and open spaces look neat.

Do not stretch too hard, because the petal shapes should stay rounded and soft.

Tips & Variations

Use white for the outline if you want the strong lace contrast shown in the image.

Try lavender, pink, blue, or yellow for the petal color.

Use cotton yarn for a tablecloth or table runner.

Use soft acrylic yarn for a baby blanket or throw.

Use finer yarn and a smaller hook for a delicate lace shawl.

Use thicker yarn and a larger hook for a cozy floral blanket.

If the petals curl, block each motif before joining.

If the white outline feels too tight, use a slightly larger hook for the white rounds.

For a more dramatic look, use black instead of white for the outline.

FAQ

Is this a granny square pattern?

It is a joined motif pattern, but it is not a traditional granny square. Each piece is a four-petal flower motif that joins into a lace fabric.

Can beginners make this pattern?

Confident beginners can make it. The motif uses basic stitches, but joining and blocking require patience.

Can I use this for a tablecloth?

Yes. Use cotton yarn and block the finished piece well so it lays flat and shows the lace spaces clearly.

How many motifs do I need?

It depends on your desired size. Make one motif, measure it, then multiply the number needed for your width and length.

Can I make it in one color?

Yes, but the two-color version makes the petal shape much clearer. A solid white version would look like delicate lace.

Conclusion

This purple petal lace crochet blanket is a beautiful project for anyone who loves floral crochet motifs and elegant openwork designs. The purple petals and white outlines create a soft lace effect that looks lovely as a blanket, tablecloth, shawl, or decorative panel.

Make a small set first to practice the joins, then keep adding motifs until your project becomes the perfect size.
