The touchable texture, cheerful colors, and swirling design make this blanket irresistible both to crochet and use!

Project Overview

This project is composed of multiple circular swirl motifs—a classic spiral pattern—each worked in two contrasting colors (navy and pink). Every motif is crocheted in the round, with careful color-changes to maintain a sharp, clean spiral. Once motifs are completed, they are joined together (either as-you-go or with a final round join) to achieve the blanket size desired. A decorative border finishes the outer edge, echoing the motif loops for a cohesive, lacy effect. Pillow covers and accents may be made with the same motifs, following similar construction principles.

Skill Level

Advanced Beginner to Intermediate: This pattern employs basic stitches, color changes, and in-round motif construction. Some attention to stitch count and color placement is needed, but adventurous beginners ready to try a spiral motif will enjoy the process.

Materials

Yarn: Sport or light DK weight cotton or soft acrylic blend. Choose vibrant contrasting shades for maximal effect.
Main Colors:
- Color A: Navy Blue (approx. 800g for a queen-size throw, about 10 skeins at 80g/skein; adjust for size)
- Color B: Bubblegum Pink (approx. 800g for similar coverage)
Crochet Hook: US size G/6 (4.0 mm) or size needed for gauge
Tapestry Needle: For weaving in ends and seaming motifs
Scissors
Stitch Markers: To mark beginnings of rounds or key joining points
Blocking Mats and Pins (optional): For shaping motifs

Finished Size

A standard blanket made with 8 x 8 spiral motifs (64 total), each measuring approximately 7 inches (18 cm) in diameter, will result in a blanket about 56 x 56 inches (142 x 142 cm), not including the decorative scallop edge (which adds 2-3 inches each side). To adjust size, add or subtract motifs or use a different hook/yarn weight for larger or smaller circles.

Gauge

One completed motif should measure roughly 7 inches (18 cm) in diameter after blocking. Gauge is not critical for this project, but consistent tension ensures uniform motifs and neat joins. Adjust hook size if motifs differ in size.

Stitches and Abbreviations

ch: chain
sl st: slip stitch
sc: single crochet
hdc: half double crochet
dc: double crochet
tr: treble crochet
inc: increase (2 sts into one st)
MR: magic ring
sp: space

Pattern Notes

Chains at the start of rounds generally count as the first stitch unless otherwise instructed.
Motifs are worked in joined rounds. Rounds begin with a starting chain (counts as first st) and end with a slip stitch to the initial chain/stitch.
Use a stitch marker to identify the first stitch of each round if needed.
Color changes are crucial for the spiral effect—change to the new color on the last yarn-over of the stitch before the color switch.
Weave in ends tightly at color joins to avoid loose or gapping transitions.
Motif placement is important for seamless joins; lay out motifs before joining the last round for best alignment.
Right side (RS) is the smoother, more defined swirl, but either can be used as ‘front’ as preferred—stay consistent throughout.

Crochet Pattern Instructions

Central Spiral Motif

With Color A (navy), make a MR: Ch 2 (counts as first hdc), 11 hdc in the ring. (12 hdc) Sl st to top of ch-2 to join. Pull ring tight.
Round 2: Ch 2, 1 hdc in same st, 2 hdc in each st around. (24 hdc) Change to Color B (pink) on last stitch. Sl st in top of ch-2 to join.
Round 3: With Color B, ch 2, 2 hdc in next st (inc), *1 hdc in next st, 2 hdc in next st repeat from * around. (36 hdc) Change back to Color A in final st. Sl st to join.
Round 4 (start spiral): With Color A, *ch 2, dc in next 3 sts, 2 dc in next st (inc); repeat from * around, ending with dc in last sts as needed to complete round (45 dc). Change to Color B in last st. Sl st to join.
Round 5: With Color B, *ch 3, tr in next 5 sts, 2 tr in next st; repeat from * around. (54 tr) Join to beginning ch or first tr. Fasten off Color B. You should see a swirl forming.

Spiral Definition and Expansion

Round 6: With Color A, join in top of any st, ch 3, 1 dc in next 6 sts, 2 dc in next st; repeat from * around. (63 dc) Sl st to join.
Round 7 (openwork): Still with Color A, ch 4 (counts as dc, ch 1), skip 1 st, *dc in next st, ch 1, skip 1 st; repeat from * around to end. (Total: 32 dc and 32 ch-1 sps) Join. Change to color B in sl st join.
Round 8 (loops and bobbles): With Color B, join with a sl st in any ch-1 sp, *ch 5, sl st in next ch-1 sp; repeat from * around. (32 loops) Sl st to base of first loop to join.

Joining Motifs

For best results, block motifs before joining.
Motifs can be joined as-you-go: Start final loop round, and at every join point (where motifs will touch), slip stitch into the adjacent motif’s loop instead of chaining the full loop.
Alternatively, finish all motifs first, then sew or sc join through corresponding loops with Color B.

Blanket Assembly

Arrange motifs in rows—8 x 8 for a standard throw.
Use spare yarn to lightly tack motifs for alignment, then use sc, whipstitch, or join-as-you-go method to secure each motif’s adjacent loops together (around 4 or 6 spots per motif, depending on arrangement).
Fill in any small gaps between motifs by whipstitching with matching yarn or work a small joining circle if needed.

Border

With Color B, join at any outer loop, *ch 3, bobble (sc, ch 3, sc) in next loop, ch 3, sl st in next loop; repeat around blanket edge. Sl st to first ch to join. Fasten off and weave in all ends.

Assembly and Finishing

After crocheting and blocking all the swirl motifs, carefully lay them out on a flat surface to arrange the final layout. Use stitch markers or scrap yarn to temporarily bind the motifs at the points where they will connect. Proceed to permanently join using your chosen method. Weave in any loose ends at color changes on the wrong side, ensuring all are secure and invisible from the front. Once joined, lightly steam or wet block the entire blanket to achieve a crisp, even finish. Shape the border scallops as you block for an elegant, lacy drape. Finally, inspect the joins to make sure there are no loose loops or gaps, then add a custom pillow cover using the same motif for a coordinated set if desired.

Customization Ideas

Play with color: Try different high-contrast combinations (white and indigo, teal and mustard, or multicolor ‘rainbow’ swirls).
Change yarn: Use sport-weight for a lighter, lacier look or worsted for thickness and warmth.
Alternate uses: Make a baby blanket (smaller motifs), shawl, oversized scarf, table runner, or pillow covers using the same motif pattern.
Add sparkle: Use a shimmering or metallic accent color for a festive effect.

Troubleshooting

Curling Motifs: If motifs curl, try increasing your hook size slightly or block motifs completely before joining.
Uneven Edges: Check your stitch count at the end of each round; missing increases will lead to tight, cupped motifs.
Blanket Too Large/Small: Adjust your hook size or add/remove rows/columns of motifs to fine-tune the total blanket dimensions.
Loose Color Changes: Always pull the new color through on the last yarn-over of previous stitch and weave ends in firmly.
Uneven Tension: Practice keeping your tension steady throughout or block aggressive areas to restore a uniform shape.

Care Instructions

If using cotton or cotton-blend yarn, machine wash on gentle in cold water with mild detergent. Lay flat or gently tumble dry on low. Avoid harsh wringing or bleaching, and reshape while damp for best results. For acrylic, machine wash and dry on medium-low, following yarn label guidance.

Final Notes

Always double-check your stitch counts at the end of each round to avoid mistakes multiplying across motifs. Tension can be adjusted as you go—don’t hesitate to frog back if shapes appear inconsistent. Use the photo as your visual guide, but don’t hesitate to introduce your own creativity for a personalized, heartfelt blanket.
