Eight turquoise petals surround a white daisy ring and golden center in this floral granny square design. This 3D flower granny square blanket crochet pattern uses DK yarn, a 4.5 mm hook, and repeated motifs to build a decorative bedspread with matching cushions. The proposed 80-square layout measures approximately 144 × 180 cm before its outer border, subject to gauge. Intermediate crochet skills are recommended because the flowers combine raised stitches, color changes, and square shaping.
The Design: What Makes This Floral Blanket Different
The turquoise granny square blanket combines three structural layers. A small yellow center anchors the white inner petals, while larger blue petals provide the dominant raised texture. Green leaf accents surround the flower before the white background converts the motif into a square.
This construction separates decorative relief from the fabric responsible for stability. White framing rounds establish repeatable joining edges, while turquoise borders make the grid visible across the bedspread.
A common mistake with dimensional floral motifs is allowing decorative stitches to replace the structural foundation. This can create uneven corners and inconsistent square measurements. The proposed design uses separate flower appliqués to keep the background flat.

3D Flower Granny Square Blanket Pattern — Step by Step
Pattern status: This is an original, photo-inspired construction proposal. It has not been physically tested. Make one sample and confirm the flower spacing, stitch counts, and dimensions before making 80 squares.
Part 1: Yellow Flower Center (Make 80)
Yarn: Golden yellow
R1: 6 sc in MR. Join with sl st. (6)
R2: Inc × 6. (12)
R3: (1 sc, inc) × 6. (18)
R4: (2 sc, inc) × 6. (24)
R5: (3 sc, inc) × 6. (30)
For a symmetrical eight-petal overlay, add two evenly distributed increases to create 32 foundation stitches. (32)
Fasten off, leaving a 15 cm yarn tail.
Part 2: White Inner Petals (Make 80 Sets)
Yarn: White
Mark eight evenly spaced anchor points on the 32-stitch foundation, four stitches apart.
For each petal, work a slip stitch at the first anchor, (hdc, 2 dc, hdc) into the next stitch, and a slip stitch into the following stitch. Repeat at the remaining marked positions, checking that each petal lies flat and that the spacing is uniform.
Make eight white petals around the yellow center. Fasten off and leave a 15 cm tail.
Part 3: Turquoise Raised Petals (Make 80 Sets)
Yarn: Turquoise blue
Attach the turquoise yarn at a marked anchor behind the white petal layer.
Petal 1: Ch 3, work 4 tr into the anchor stitch, ch 3, and sl st into the same anchor. (4 tr, 6 ch, 1 sl st)
Repeat at the remaining seven anchors, fastening off and rejoining yarn as needed to keep the petals separate.
Make eight raised turquoise petals. Keep the anchor tension loose enough to prevent the yellow center from puckering.
Part 4: Green Crochet Leaves (Make 4–8 per Square)
Yarn: Leaf green
Ch 7.
R1: Starting in the second chain from the hook, work sl st, sc, hdc, dc, hdc, sc. (6 sts)
R2: Rotate and work along the opposite side of the chain: sc, hdc, dc, hdc, sc, sl st. (6 sts)
Fasten off, leaving a 20 cm tail.
Position the leaves between the turquoise petals. Four leaves create a simpler arrangement; eight produce a fuller botanical appearance.
Part 5: White Granny Square Background (Make 80)
Yarn: White
Work a separate granny square as the structural background. The raised flower will be sewn onto it after blocking.
R1: MR, ch 3 (counts as dc), 2 dc, ch 2. Work (3 dc, ch 2) three more times into the ring. Join. (12 dc, 4 corner spaces)
R2: In each corner, work (3 dc, ch 2, 3 dc), placing ch 1 between corner groups. (24 dc)
R3: Repeat the corner groups and work 3 dc in each side ch-1 space, with ch 1 between groups. (36 dc)
R4: Continue the granny-square expansion. (48 dc)
R5: Repeat. (60 dc)
R6: Repeat. (72 dc)
R7: Repeat. (84 dc)
R8: Repeat. (96 dc)
Fasten off. Check the actual dimensions and adjust the number of rounds if needed.
Part 6: Turquoise Square Border (Make 80)
Yarn: Turquoise blue
R1: Join turquoise yarn at a corner. Work (sc, ch 2, sc) into the corner space. Continue with sc along each side, placing matching corner groups at the other three corners. Join with sl st.
R2: Work one sc into each stitch around, with (sc, ch 2, sc) in each corner space. Join.
Fasten off, leaving a 25 cm tail if using the edging yarn for joining.
Gauge checkpoint: The target is approximately 18 × 18 cm per blocked square, including edging.
Part 7: Optional White Accent Circles
Yarn: White
R1: 6 sc in MR. (6)
R2: Inc × 6. (12)
Fasten off, leaving a 15 cm tail. These optional appliqués are not required for the reference design.
Part 8: Matching Floral Crochet Pillow Covers (Make 2)
The reference image includes two matching pillows. Each proposed pillow front uses four floral granny squares arranged in a 2 × 2 layout.
- Make four complete floral squares per pillow.
- Block all squares to identical dimensions.
- Join the squares into a square front panel.
- Measure the completed front.
- Crochet a plain back panel to the same dimensions.
- Join the front and back along three sides.
- Insert the cushion and finish the closure.
With 18 cm squares, the front measures approximately 36 × 36 cm before additional edging.
How to Assemble the Crochet Flower Blanket
- Block the first square. Measure the finished dimensions after drying.
- Complete the motifs. Make 80 matching squares for an eight-column, ten-row arrangement.
- Attach the flowers. Center each raised flower on its background square and sew through the foundation stitches.
- Arrange the squares. Keep leaf orientation and flower placement consistent.
- Pin the first row. Align eight squares and match the corner spaces.
- Join the squares. Use mattress stitch or a slip-stitch seam.
- Connect the rows. Join all ten rows, aligning the vertical seams.
- Add the outer border. Crochet one or more sc rounds around the blanket.
- Finish the pillow covers. Attach the back panels and chosen closures.
- Weave in ends and block. Secure loose yarn tails and finish according to the yarn care instructions.
The completed project consists of a floral granny square blanket and two coordinated cushion covers.
7 Technical Tips for Better Floral Granny Squares
- Stitch markers: Mark all four corners before working the background. A missing corner space can distort the square and create uneven joining edges.
- Square measurements: Check every tenth square against the 18 cm target. Even a 5 mm variation per square can create several centimeters of difference across a large blanket.
- Petal tension: Avoid pulling the turquoise treble stitches too tightly. Excess tension can make the raised petals curl inward and distort the flower center.
- Flower positioning: Pin each flower to the center of its background before sewing. Off-center flowers become more noticeable when repeated in a grid.
- Leaf placement: Position leaves at consistent distances from the yellow center. Uneven leaf angles can make neighboring motifs appear rotated.
- Joining seams: Match the corner spaces and corresponding edge stitches before joining. Skipped stitches can create puckering along the turquoise borders.
- Yarn tails: Leave at least 15 cm for securing small appliqués. Short tails may loosen after repeated washing or handling.
Conclusion
The proposed 3D flower granny square blanket crochet pattern uses separate floral overlays, white structural squares, and turquoise joining edges to reproduce the main visual features of the reference image. Its modular construction also supports matching cushion covers, alternative blanket dimensions, and individual square replacements. Before committing to 80 motifs, complete one sample, check the petal spacing, measure the blocked square, and weigh the yarn used.
Save the finished sample and color arrangement to Pinterest, or share progress photographs on Instagram using #3DFlowerGrannySquareBlanket. Record the final gauge so future squares remain consistent.
Would you use four green leaves or eight around each turquoise flower?
