Abbreviations

Spiral Centre (make 30)

1. Round 1: Make a MR. With gold, ch 1, 2 hdc in ring; drop gold. Join cream in ring, 2 hdc in ring; drop cream. Join navy in ring, 2 hdc in ring. Pull the ring tight. (6 hdc — 2 per colour)
2. From here work in a continuous spiral, never joining. Each colour works its own segment, is dropped, and the next colour works over the dropped strands. Always keep the colours in the same order: gold, cream, navy.
3. Round 2: With each colour in turn: 2 hdc in each of next 2 sts. (4 sts per colour — 12 total)
4. Round 3: With each colour in turn: (2 hdc in next st, hdc in next st) x2. (6 per colour — 18 total)
5. Round 4: With each colour in turn: (2 hdc in next st, hdc in next 2 sts) x2. (8 per colour — 24 total)
6. Round 5: With each colour in turn: (2 hdc in next st, hdc in next 3 sts) x2. (10 per colour — 30 total)
7. Round 6: With each colour in turn: (2 hdc in next st, hdc in next 4 sts) x2. (12 per colour — 36 total)
8. Round 7: With each colour in turn: (2 hdc in next st, hdc in next 5 sts) x2. (14 per colour — 42 total)
9. Round 8: With each colour in turn: (2 hdc in next st, hdc in next 6 sts) x2. (16 per colour — 48 total)
10. Round 9 (levelling round, no increases): With each colour in turn: hdc in next 13 sts, sc in next 2 sts, sl st in next st, then FO that colour. The sc-to-sl st taper steps each arm down so the outer edge sits flat. (48 stitch positions)
11. Weave the three tail ends in on the back before you go further — they are much harder to reach once the navy rim is on.

Wheel Rounds (on each motif)

1. Round 10: Join navy with a sl st in any st, ch 1, sc in each st around, sl st to first sc. (48)
2. Round 11: Ch 2, (2 dc in next st, dc in next st) x24, sl st to top of ch 2. FO navy. (72)
3. Round 12 (spoke round): Join slate blue in any st, ch 4 (counts as dc + ch 1), skip next st, *dc in next st, ch 1, skip next st*, rep from * around, sl st to 3rd ch of ch 4. (36 dc and 36 ch-1 sps — 72 positions)
4. Round 13: Ch 1, sc in each dc and 1 sc in each ch-1 sp around, sl st to first sc. FO slate blue. (72)
5. Round 14 (bobble ring): Join gold in any st, ch 1, *sc in next 2 sts, bobble in next st*, rep from * around (24 reps), sl st to first sc. FO gold. (72 sts, 24 bobbles)
6. Push every bobble through to the front of the work with your thumb before moving on — once the cream frame is attached they will not pop out cleanly.

Cream Square Frame (on each motif)

1. Round 15 (squaring round): Join cream in any sc that sits directly before a bobble. Ch 1, then *(3 dc, ch 2, 3 dc) in next st [corner made], dc in next 2 sts, hdc in next 3 sts, sc in next 7 sts, hdc in next 3 sts, dc in next 2 sts*, rep from * 3 more times, sl st to first dc. Each repeat uses 18 stitches of Round 14, so the four corners land 18 sts apart. (92 sts and 4 ch-2 corner sps — 23 sts per side)
2. Round 16: Ch 2, *(2 dc, ch 2, 2 dc) in corner ch-2 sp, dc in next 11 sts, 2 dc in next st, dc in next 11 sts*, rep from * 3 more times, sl st to top of ch 2. FO, leaving a 20 cm tail if you plan to join by sewing. (112 sts and 4 ch-2 corner sps — 28 sts per side)
3. Block each finished motif to a true 20 cm square, pinning the four ch-2 corners first and then easing the sides straight. Do not skip this — unblocked motifs cup slightly from the bobble ring and the seams will ripple.
4. Make 30 motifs in total for a 5 x 6 layout.

Joining the Motifs

1. Lay all 30 blocked motifs out in 6 rows of 5. Rotate a few of them so the spiral arms do not all point the same way — the scattered swirl directions are what give the blanket its movement.
2. Join in rows first. Hold two motifs with wrong sides together. With cream and the tapestry needle, whip stitch through the back loops only of both motifs, working 1 stitch into each of the 28 sts along the side and 1 stitch into each of the two ch-2 corner sps. (30 whip stitches per seam)
3. Continue across until each row of 5 motifs is joined. You will have 6 long strips.
4. Join the strips the same way, working the full length of each seam in one pass: 5 motifs x 30 stitches = 150 whip stitches per long seam. At each four-corner junction, pass the needle through all four ch-2 spaces once so no hole forms.
5. Weave in all joining tails along the seam line on the back, then give the joined blanket a light steam-block flat before adding the border.

Bobble Garlands (make 20)

1. Step 1: With cream, ch 4.
2. Step 2: Bobble in 4th ch from hook, ch 4.
3. Step 3: Change to gold, bobble in 4th ch from hook, ch 4.
4. Step 4: Change back to cream, bobble in 4th ch from hook, ch 4.
5. Step 5: Rep Steps 3 and 4, alternating gold and cream, until the garland has 7 bobbles in total, ending with a cream bobble. Ch 1 and FO, leaving a 25 cm sewing tail. Each finished garland measures about 18 cm.
6. Carry the unused colour loosely along the chain stems rather than cutting it at every bobble — it hides inside the chain and saves 12 ends per garland.
7. Make 20 garlands.

Border

1. Round 1: Join cream in any blanket corner ch-2 sp. Ch 1, 3 sc in that corner sp, then sc in each st along each motif side (28 per side) and 2 sc into each seam junction where two motif corners meet, placing 3 sc in each of the remaining 3 blanket corners. Sl st to first sc. (148 sc on each short edge, 178 sc on each long edge, 12 corner sc — 664 total)
2. Round 2 (spoke round): Join slate blue in the centre sc of any corner, ch 4, dc in same st, ch 2, dc in same st — wait at the corner only: work (dc, ch 2, dc) in each corner centre st. Along the edges work *dc in next st, ch 1, skip next st*. Sl st to join. (338 dc, 330 ch-1 sps, 4 ch-2 corner sps)
3. Round 3: Join cream in any ch-1 sp, ch 1, sc in each dc and 1 sc in each ch-1 sp around, 3 sc in each corner ch-2 sp, sl st to first sc. FO cream. (680)
4. Round 4 (bobble round): Join gold in the first sc after any corner, ch 1, *sc in next 3 sts, bobble in next st*, rep from * around (170 reps), sl st to first sc. FO gold. (680 sts, 170 bobbles)
5. Round 5: Join navy in any st, ch 1, sc in each sc and in the top of each bobble around, working 3 sc in each corner st, sl st to first sc. FO navy. (692)
6. Pull every border bobble to the right side as you go, then block the border edge straight with pins while the blanket is damp.

Finishing

Pin the bobble garlands along the seam lines before you sew anything. Place them in gentle arcs that follow the curve of the wheels rather than in straight lines — two or three per horizontal seam, tucked into the cream frame corners where four motifs meet. Step back and look at the whole blanket from a distance before committing; the garlands read as scattered berries, and they look best when they are not evenly spaced.

Sew each garland down with the cream tail and a tapestry needle, catching only the chain stems between the bobbles so the bobbles themselves stay loose and round. Two or three stitches per stem is plenty. Secure the tail on the back with a small knot and run it under the seam stitching for 5 cm before trimming.

Weave in every remaining end, then give the finished blanket a full wet block: soak in cool water, roll in a towel to press out the excess, and pin flat to 120 x 140 cm with the corners square. Let it dry completely, which usually takes a day. The bobbles flatten slightly during blocking and spring back once dry. Wash it on a cool gentle cycle afterwards and dry flat — a cotton blanket this size will stretch badly if you hang it wet.

Tips for Success

• Use three different coloured stitch markers in the spiral centre, one per arm, and move each one up as you finish that colour’s segment. This single habit prevents nearly every spiral error.
• Make the first three motifs, block them, and measure before you cut more yarn. If they come out at 19 cm, go up to a 4.5 mm hook; at 21 cm, drop to 3.5 mm. A 1 cm difference per motif adds up to 6 cm across the blanket.
• Work all 30 spiral centres first in one sitting-stretch, then all the navy rims, then all the spoke rounds. Batch working keeps tension consistent across motifs far better than finishing them one at a time over several weeks.
• Keep the ch-1 spaces in the spoke rounds loose and even. Tight chains pull the spokes into a star shape instead of a wheel, and it shows immediately next to a correctly worked motif.
• Block in batches of six on the same mat layout with the same pin positions, so every motif ends up genuinely identical rather than approximately so.

Common Mistakes to Avoid

• Joining a new colour each round instead of carrying it. The three spiral strands stay live for all nine rounds. If you cut and rejoin, the arms step instead of curving and you get 54 extra ends per motif.
• Skipping the levelling round. Round 9 is what makes the spiral edge flat. Without it the navy rim sits over a visible staircase and the motif will never block square.
• Bobbles popping to the wrong side. They form on the back of the work as you make them. Push each one through to the front before you work the next stitch — chasing them afterwards distorts the surrounding stitches.
• Placing the Round 15 corners randomly. The four corners must sit 18 stitches apart. Count them out and mark all four positions before you start the round, or you will end up with a lopsided square that fights its neighbours at the seam.
• Joining with the right sides together. This pattern uses a back-loop whip stitch with wrong sides together, which leaves a soft raised ridge on the front that frames each wheel. Joining the other way buries the detail.

Ways to Customize This Pattern

• Lap blanket: make 9 motifs in a 3 x 3 layout for a 70 x 70 cm throw. The border counts become 100 sc per edge in Round 1; everything else is worked exactly as written.
• Two-tone spiral: drop one colour from the centre and work a two-arm spiral instead, starting with 2 hdc per colour in the ring and increasing by 2 per colour per round. The swirl becomes wider and bolder, and it reads better from across a room.
• Calmer palette: keep the cream and slate blue, and swap navy and gold for charcoal and dusty rose. The construction carries the design, so almost any four-colour scheme with one dark, one bright, one mid and one light works.
• No bobbles: replace the Round 14 bobble with a dc for a flatter blanket that is easier to wash and far faster to make. Skip the garlands and work the border bobble round as plain sc.
• Matching cushion front: work four motifs, join them 2 x 2, add Border Rounds 1 to 4 only, and back it with a plain cream dc panel for a 45 cm cushion cover.
