Instructions

Main Octagon Mandala Motif — Dusty Mauve & Charcoal Grey (make ~70 motifs for Queen size)

Each octagonal motif transitions through 8-sided geometry: starting with a dusty mauve central flower ring, overlaying charcoal slate grey front-post star spokes, and framing with a solid mauve 8-sided border[cite: 1].

Part 1: 8-Pointed Starburst Center (Colors A & B)

1. Round 1 (Center Core Ring – Color A Mauve): With Color A (Dusty Mauve), make a magic ring (or ch 6, sl st to join)[cite: 1]. Ch 1, work 16 sc into the ring[cite: 1]. Join with sl st to first sc[cite: 1]. Pull ring tail tight[cite: 1]. [16 sc]
2. Round 2 (Inner Petal Ring – Color A Mauve): Ch 3 (counts as dc), dc in same st, work 2 dc in each st around[cite: 1]. Join with sl st to top of starting ch-3[cite: 1]. [32 dc]
3. Round 3 (Establishing 8 Star Points – Color B Charcoal): Attach Color B (Charcoal Grey) in any st[cite: 1]. *Work 1 FPdc around next dc, ch 2, skip 1 st, 3 dc in next st, ch 2, skip 1 st; repeat from * 7 more times around[cite: 1]. Join with sl st[cite: 1]. [8 FPdc spokes, 8 3-dc clusters, 16 ch-2 sps]
4. Round 4 (Expanding Star Spokes – Color B Charcoal): *FPtr around Round 3 FPdc, ch 2, 5 dc in center of 3-dc cluster, ch 2; repeat from * 7 more times around[cite: 1]. Join with sl st, fasten off Color B[cite: 1]. [8 FPtr spokes, 8 5-dc fan petals]

Part 2: Octagon Framing & Solid Border (Color A Dusty Mauve)

1. Round 5 (Mauve Flower Petal Infill – Color A Mauve): Attach Color A (Dusty Mauve) in any ch-2 sp beside a charcoal spoke[cite: 1]. *Work 3 dc in ch-2 sp, 1 dc in BLO of each of the 5 fan sts, 3 dc in next ch-2 sp, ch 1 over charcoal spoke; repeat from * 7 more times around[cite: 1]. Join with sl st[cite: 1]. [88 dc total]
2. Round 6 (8-Corner Octagon Expansion – Color A Mauve): *In ch-1 sp over spoke work [2 dc, ch 2, 2 dc] to establish an octagon corner point, dc in next 11 sts; repeat from * 7 more times around all 8 sides[cite: 1]. Join with sl st[cite: 1]. [120 dc, 8 corner ch-2 sps]
3. Round 7 (Solid Octagon Border – Color A Mauve): Ch 3 (counts as dc), work 1 dc in each st around, working [2 dc, ch 2, 2 dc] into each of the 8 corner ch-sps[cite: 1]. Join with sl st, fasten off Color A, and weave in all loose ends securely[cite: 1]. [152 dc; Motif diameter across flat sides = ~22 cm]

Small Square Gap Fillers — Charcoal Grey (make ~54 filler motifs)

Because octagons leave square gaps when joined edge-to-edge, these small charcoal square motifs fill the negative space intersections seamlessly[cite: 1].

1. Round 1 (Color B Charcoal): With Color B (Charcoal Grey), make a magic ring[cite: 1]. Ch 3 (counts as dc), work [2 dc, ch 2, 3 dc, ch 2, 3 dc, ch 2, 3 dc, ch 2] into ring[cite: 1]. Join with sl st to top of starting ch-3[cite: 1]. [4 3-dc clusters, 4 corner ch-2 sps]
2. Round 2: Sl st into corner sp[cite: 1]. Ch 3, work [2 dc, ch 2, 3 dc] in corner sp, ch 1, 3 dc in next st, ch 1, *[3 dc, ch 2, 3 dc] in corner sp, ch 1, 3 dc in next st, ch 1; repeat from * 2 more times around[cite: 1]. Join with sl st, fasten off leaving a 25 cm tail for seaming[cite: 1]. [Square size = ~8 x 8 cm]

Bedspread Assembly

1. Arrangement: Lay out all 70 main octagonal motifs on a clean, flat surface in a 7 x 10 grid, ensuring all 8-pointed grey starbursts line up uniformly across the mattress top[cite: 1].
2. Octagon Seaming: Place touching octagons right sides together[cite: 1]. Using Color A (Dusty Mauve) yarn and a tapestry needle, whipstitch touching flat sides together through the back loops only (BLO)[cite: 1].
3. Inserting Square Fillers: Position a Small Charcoal Square Filler into each 4-way intersection gap between octagons[cite: 1]. Hand-sew the 4 edges of each small square to the adjacent short sides of the 4 surrounding octagons using the charcoal yarn tail[cite: 1].

Continuous Outer Scalloped Bedspread Border

1. Round 1 (Base Anchor Row – Color B Charcoal): Attach Color B (Charcoal Grey) yarn in any outer point along the assembled bedspread[cite: 1]. Ch 1, work single crochets evenly around all 4 outer edges, placing 3 sc into outer corner points and 1 sc dec in inner seams where motifs meet[cite: 1]. Join with sl st[cite: 1].
2. Round 2 (Open Mesh Band – Color A Mauve): Switch to Color A (Dusty Mauve)[cite: 1]. Ch 4 (counts as dc + ch 1), *skip 1 st, dc in next st, ch 1; repeat around entire outer perimeter, working [2 dc, ch 2, 2 dc] into outer corners[cite: 1]. Join with sl st[cite: 1].
3. Round 3 (Scalloped Outer Border – Color A Mauve): *In corner ch-sp work [5 dc, picot, 5 dc], sc in next ch-sp, *skip 2 sts, work [4 dc, picot, 4 dc] in next ch-sp, sc in next ch-sp; repeat from * continuously around all 4 sides of the bedspread to form the draped scalloped edging[cite: 1]. Join with sl st, fasten off, and weave in all remaining loose ends[cite: 1].

Matching Decorative Pillow Shams (make 2)

Front Sham Panel

1. Join 4 main Octagon Mandala Motifs in a 2×2 square formation with 1 Small Charcoal Square Filler in the center gap using Color A (Dusty Mauve)[cite: 1].
2. Work Round 6 and Round 7 of the octagon instructions around the perimeter of the 2×2 block to square off the panel to ~45 x 45 cm[cite: 1].

Back Sham Panel

1. Row 1: With Color A (Dusty Mauve), ch 57[cite: 1]. Dc in 4th ch from hook and in each ch across[cite: 1]. Turn[cite: 1]. [55 dc]
2. Rows 2–32: Ch 3 (counts as dc), 1 dc in each st across[cite: 1]. Turn[cite: 1]. Fasten off after Row 32 [55 dc per row; ~45 x 45 cm square][cite: 1].

Sham Assembly

Place front and back panels wrong sides together[cite: 1]. Single crochet around 3 sides using Color A, insert a 45 x 45 cm pillow form, and sc across the 4th side to seal[cite: 1]. Finish with a grey scalloped picot border around all 4 outer sham edges[cite: 1].

Tips for Success

• Maintain Uniform Post-Stitch Tension: Keep even tension on charcoal front-post double/treble stitches in Rounds 3 and 4 so that the star spokes lay flat without pulling the motif core into a cupped shape[cite: 1].
• Steam Block Individual Octagons: Steam-blocking each 8-sided motif to ~22 cm across before assembly flattens the edges, aligns the corner angles, and makes row-by-row seaming much faster[cite: 1].
• Weave In Color Ends As You Go: Fasten off and weave in loose ends at each color switch during motif construction to avoid a tedious finishing workload at the end[cite: 1].
• Keep Seaming Stitches Relaxed: Avoid pulling joining threads too tightly so that the octagon and square filler seams lie completely flat without buckling[cite: 1].
• Choose a High-Definition Smooth Yarn: A smooth acrylic or cotton-blend yarn showcases the crisp color contrast between the mauve star petals, charcoal spokes, and square gap fillers[cite: 1].

Common Mistakes to Avoid

• Skipping Motif Blocking — Unblocked 8-sided motifs pull inward at the post-stitch spokes, causing puckered, uneven seams during assembly[cite: 1].
• Miscounting Octagon Side Stitches — Missing a double crochet along any of the 8 outer sides in Round 6 will warp the geometric symmetry when joining filler squares[cite: 1].
• Uneven Seaming Tension — Seaming too tightly along the motif joints creates rigid ridges instead of a flat blanket surface[cite: 1].
• Mixing Yarn Dye Lots — Ensure all skeins of dusty mauve pink and charcoal slate grey share matching dye lots to prevent noticeable shading differences across the broad background[cite: 1].

Ways to Customize This Pattern

• Cream & Sage Botanical Palette: Swap charcoal slate grey for forest sage green and dusty mauve for warm cream yarn to create a natural woodland aesthetic[cite: 1].
• Throw Blanket Dimension: Reduce motif count to 35 octagons (5 x 7 grid) with 24 gap fillers to create a cozy living room throw (~110 x 150 cm)[cite: 1].
• Matching Octagon Coasters & Trivets: Work single octagon motifs in heavy cotton yarn to craft matching geometric hot pads or table trivets[cite: 1].
