If you enjoy projects that blend visual beauty with rewarding technique, this sunflower blanket will be an unforgettable addition to your crochet repertoire.

Project Overview

This blanket is constructed from individual granny squares, each showcasing a large, layered sunflower motif with a central circle, two graduated rounds of petals (orange and yellow), and two green leaves attached per square. The motifs are bordered with white (or a pale neutral) and then joined together. After assembling the blanket, a simple border is added. The blanket is completed by sewing in any remaining ends and lightly blocking for a crisp finish.

Skill Level

Intermediate: This project involves working in the round, color changes, layered motifs, post stitches, join-as-you-go, and shaping for the leaves and petals. Confident advanced beginners with experience changing colors and following motif instructions can also succeed with careful attention.

Materials

• Yarn: Worsted weight (Category 4) cotton or acrylic yarn recommended for vivid color and durability.
• Color amounts per motif (approx):
  • Center (Dark Brown): 10 g (approx. 18 yds/16 m)
  • Inner Petals (Orange): 15 g (approx. 27 yds/25 m)
  • Outer Petals (Yellow): 20 g (approx. 36 yds/33 m)
  • Leaves (Medium to Dark Green): 10 g (approx. 18 yds/16 m for two leaves)
  • Square and Join Color (White or Cream): 25 g (approx. 45 yds/41 m per square)
• For a single sunflowers blanket (5 x 5 motifs): Multiply the above by 25.
• Crochet Hook: US H-8 (5 mm) or size needed for gauge.
• Tapestry needle (for sewing leaves and weaving in ends).
• Scissors, stitch markers (for marking rounds and joins).

Finished Size

Each sunflower square measures approximately 8.5 x 8.5 inches (22 x 22 cm) including petals and border. A blanket with 25 squares (5 x 5) measures about 42 inches (107 cm) on each side, excluding the optional blanket edge. Adjust the number of squares for a larger or smaller blanket. Petals can also be reduced/enlarged for a size change.

Gauge

Gauge is approximately 13 sc and 14 rows in 4 inches (10 cm) of the flat round sunflower center (before adding petals). Exact gauge is not crucial, but consistent tension helps motifs and assembly.

Stitches and Abbreviations

• ch: chain
• sl st: slip stitch
• sc: single crochet
• hdc: half double crochet
• dc: double crochet
• tr: treble crochet
• MR: magic ring
• inc: increase (2 sts in same st)
• dec: decrease (2 sts together)
• RS: right side

Pattern Notes

• Chains at the start of rounds do not count as stitches unless specified.
• Work flower center and petals in joined rounds.
• Always join rounds with a sl st to the first st unless stated otherwise.
• For a neat color change, finish the last st of old color by pulling through with new color.
• Hold petals forward for layering; attach leaves before working the square border so bases are hidden.
• Use stitch markers to mark the start of rounds or petal placements if preferred.
• The right side (RS) is the public side of the motif; keep all petals and leaves facing outward on RS.

Crochet Pattern Instructions

Center of Sunflower (Brown)

1. With dark brown, make a MR. Ch 1, work 8 sc into ring. Pull tight and sl st to first sc to join. (8 sts)
2. Ch 1, 2 sc in each st around. Sl st to join. (16 sts)
3. Ch 1, *sc in next st, 2 sc in next st*; rep * to * around. Sl st to join. (24 sts)
4. Ch 1, *sc in next 2 sts, 2 sc in next st*; rep * to * around. Sl st to join. (32 sts)
5. Ch 1, *sc in next 3 sts, 2 sc in next st*; rep * to * around. Sl st to join. (40 sts)
6. Ch 1, *sc in next 4 sts, 2 sc in next st*; rep * to * around. Sl st to join but pull orange through last sl st to begin first petal round. (48 sts)

Inner Petals (Orange)

7. Attach orange. First Layer of Petals (Make 16): Ch 2, skip 2, in next st work (dc, tr, dc), ch 2, sl st in same st. Sl st into next st.
   Repeat from * for each petal:
   Sl st in next st, ch 2, skip 2, in next st (dc, tr, dc), ch 2, sl st in same st, sl st in next st. Continue around for 16 petals. Join with sl st to first ch 2. Fasten off orange.

Outer Petals (Yellow)

8. Join yellow in any unworked inner round st between orange petals. Work behind orange petals. Ch 3, in next unworked st (tr, dc, tr), ch 3, sl st in same st. Sl st in next st. Repeat around to make 16 large yellow petals. Join with sl st, fasten off and weave in ends.

Sunflower Leaves (Make 2 per square, Green)

9. With green, ch 11.
10. Row 1: Sc in 2nd ch from hook and next 8 ch (9 sc), turn.
11. Row 2: Ch 1, sc in same, hdc in next, dc in next 4, hdc in next, sc in last 2, turn.
12. Row 3: Ch 1, sc2tog, hdc, dc2tog, dc2tog, hdc, sc2tog. (7 sts). Fasten off and leave a tail for sewing.
13. With RS facing and using tail, attach leaves to sides of sunflower at the square’s diagonal corners (so two leaves diagonally opposite). Secure with a few stitches behind petals.

Granny Square Border (White or Cream)

14. With white/cream, attach yarn to any outer petal base (behind petal). Ch 3 (counts as dc), work 1 dc in same space. Work one dc in base of each petal and in center between petals all the way around.
15. At 4 evenly spaced points (for corners), work [2 dc, ch 2, 2 dc] in same st to form a corner.
    After first round border, you should have a neat square of dc stitches. Join with sl st to top of beg ch-3, fasten off.
    Repeat for each motif.

Joining Squares

16. Lay out your squares in a pleasing arrangement (5 x 5 for a 25-square throw).
17. Use your preferred method to join: single crochet (sc), slip stitch, or whipstitch through back loops only, using white or the chosen join color. Work row by row, then column by column, ensuring leaves and petals face up and outwards. Weave in ends as you go for a neat finish.

Blanket Border (Optional)

18. With white, after joining all squares, work around the entire blanket:
    Round 1: Ch 3, dc in each st and ch-space, (2 dc, ch 2, 2 dc) in each corner.
    Rounds 2-3: Repeat before, or work a row of sc or a decorative edge of your choice (eg: picot or shell).
19. Fasten off and weave in final ends.

Assembly and Finishing

Once all the granny squares are complete and joined, check that all petals and leaves are pointing neatly outward and not caught in joins. Weave in any remaining yarn tails firmly with a tapestry needle on the WS (wrong side) of the blanket. Gently shape the petals and leaves by hand, pulling them forward if needed for fullness.

For the best finish, lightly block the blanket. Lay it flat on a clean towel, spray with water until just damp, and gently pat each square and petal into shape, focusing on even corners and crisp petal curves. Let air dry fully. Shaping the petals upwards creates the lovely 3D effect. For extra structure, you may also steam the petals briefly, carefully avoiding too much heat, especially if using acrylic yarn.

Customization Ideas

• Color Variations: Try different petal shades like pale yellow, deep gold, or burnt orange for a seasonal effect. Blues or reds for a fantasy flower look.
• Blanket Size: Adjust the blanket by making more or fewer squares, following the same joining and border process. Make matching cushions with a single motif.
• Other Uses: Turn a single motif into a statement potholder, table mat, or wall hanging. Use finer yarn and a smaller hook for delicate coasters.

Troubleshooting

• Petals Curling Excessively: This is natural for some petals. Blocking and gentle shaping with steam or damp hands helps control this and produce fuller, upright petals.
• Uneven Edges: If your granny squares are warping, check your stitch count around the border and adjust as you go. Ensure corner increases are consistent.
• Size Incorrect: Blanket too large/small? Adjust hook size—smaller hook for a tighter, smaller piece; larger for looser, larger one. Changing yarn weight also changes overall size.
• Loose Color Changes: Finish old color by joining new color in the last yarn-over of previous stitch for a seamless transition.
• Inconsistent Tension: Take breaks to relax your hands and try using a yarn bowl or tension ring to help keep yarn feeding evenly.

Care Instructions

Machine wash the finished blanket on a gentle cycle in cold water (30°C/86°F) using mild detergent. Lay flat or drape to dry, avoiding a heated dryer, which may distort the 3D petals. For best results with cotton, shape the petals and squares while damp. Store flat or loosely folded to preserve texture.

Final Notes

Double-check motif stitch counts at each step for uniformity, and adjust tension if you notice warping or uneven petals. Working each motif individually allows for creative flexibility and easier assembly. Use the photo as a guide to ensure the visual consistency of each cheerful sunflower. Enjoy making your blanket—a true piece of crochet artistry!
