The Frosted Bloom Granny Square is a single winter flower motif in dusty blue and cream. Eight plump blue puff petals sit around a small cream center. A lacy cream ring frames them, and blue treble fans and a crisp blue edge square it off.
The palette is calm and wintry: soft blue for the petals and frame, warm cream for the center and lace ring. It looks especially pretty displayed on point, like a diamond.
This pattern uses US crochet terms. The finished square measures 6 in x 6 in (15.2 cm x 15.2 cm) after blocking.
Construction is simple. You work seven rounds from a magic ring: a cream center, a blue puff petal round, two cream lace rounds, a blue squaring round, and a two-round blue border. Some makers string several squares on a chain cord as a garland, but this pattern covers one square.

Special stitches
Puff (petal puff): [Yo, insert hook in st, yo, pull up a loop to about 0.75 in (1.9 cm)] 5 times (11 loops on hook). Yo, draw through 10 loops, yo, draw through the remaining 2 loops, ch 1 to close. The closing ch 1 forms the pointed petal tip and does not count as a stitch.
Cl (3-dc cluster): [Yo, insert hook in sp, yo, pull up a loop, yo, draw through 2 loops] 3 times, yo, draw through all 4 loops.
Beg cl: Ch 2, then [yo, insert hook in sp, yo, pull up a loop, yo, draw through 2 loops] 2 times, yo, draw through all 3 loops. Counts as 1 cl.
Gauge and Checkpoints
You measure gauge on the motif itself. Make one test square first and check it at each stage.
- After Round 2: flower measures 2.5 in (6.4 cm) across, petal tip to petal tip.
- After Round 4: cream ring measures 4.25 in (10.8 cm) across.
- After Round 5: square measures 5 in (12.7 cm) per side.
- After Round 7: square measures 6 in (15.2 cm) per side.
Border gauge: 16 dc = 3 in (7.6 cm) along the edge in Round 6.
If your square is too big: go down one hook size to 4.0 mm (US G-6), and pull petal loops slightly shorter.
If your square is too small: go up one hook size to 5.0 mm (US H-8).
Blocking can usually fix a difference of 0.25 in (0.6 cm) or less.
Pattern
Round 1 (Color B, cream): Center
Make a magic ring.
Ch 3 (counts as dc), work 15 dc in ring. Pull the ring closed, leaving a small hole about 0.25 in (0.6 cm) wide. Join with sl st to top of ch-3.
Stitch count: 16 dc.
Fasten off Color B.
Round 2 (Color A, blue): Puff Petals
Join Color A in any dc with a sl st.
Ch 2 (does not count as a stitch), puff in same st, ch 3, sk next dc. *Puff in next dc, ch 3, sk next dc; repeat from * 6 more times. Join with sl st to top of first puff.
Stitch count: 8 puffs, 8 ch-3 sps.
You work the puffs in every other dc, so the 16 dc of Round 1 give exactly 8 petals. Each petal should look like a plump leaf pointing outward.
Fasten off Color A.
Round 3 (Color B, cream): V-Shells
Join Color B in any ch-3 sp.
Ch 3 (counts as dc), (dc, ch 2, 2 dc) in same sp, ch 1. *(2 dc, ch 2, 2 dc) in next ch-3 sp, ch 1; repeat from * 6 more times. Join with sl st to top of ch-3.
Stitch count: 32 dc (8 shells of 4 dc), 8 ch-2 sps, 8 ch-1 sps.
Each shell sits between two petals, and each ch-1 sp sits directly above a petal.
Do not fasten off.
Round 4 (Color B, cream): Paired Clusters
Sl st in next dc and into the ch-2 sp.
Beg cl in same sp, ch 2, cl in same sp. Ch 2, sc in next ch-1 sp, ch 2. *(Cl, ch 2, cl) in next ch-2 sp, ch 2, sc in next ch-1 sp, ch 2; repeat from * 6 more times. Join with sl st to top of beg cl.
Stitch count: 16 cl, 8 sc, 24 ch-2 sps.
The ch-2 sp between each cluster pair is a “tip” sp. There are 8 tip sps. Four become corners and four become side middles.
Checkpoint: the cream ring measures 4.25 in (10.8 cm) across.
Fasten off Color B.
Round 5 (Color A, blue): Squaring Round
Join Color A in any tip sp. This is your first corner.
Ch 4 (counts as tr), (3 tr, ch 3, 4 tr) in same sp.
Side sequence: ch 2, dc in next ch-2 sp, ch 2, dc in next ch-2 sp, ch 2, 3 dc in next tip sp, ch 2, dc in next ch-2 sp, ch 2, dc in next ch-2 sp, ch 2.
Corner: (4 tr, ch 3, 4 tr) in next tip sp.
Work the side sequence, then *corner, side sequence; repeat from * 2 more times. Join with sl st to top of ch-4.
Stitch count: 60 sts (32 tr + 28 dc), 24 ch-2 sps, 4 ch-3 corner sps.
Per side, between corner ch-3 sps: 4 tr + 7 dc + 4 tr = 15 sts, plus 6 ch-2 sps.
The tall treble fans fill the corners. The shorter dc and chain spaces keep the sides flat and open.
Checkpoint: 5 in (12.7 cm) per side.
Do not fasten off.
Border
The border is two blue rounds. Round 6 builds a solid dc frame. Round 7 adds a firm sc edge and pointed corners.
Border gauge: 16 dc = 3 in (7.6 cm).
Round 6 (Color A): Solid Double Crochet
Sl st in next 3 tr and into the corner ch-3 sp.
Ch 3 (counts as dc), (dc, ch 2, 2 dc) in same sp. *Dc in each st and 2 dc in each ch-2 sp across to next corner, (2 dc, ch 2, 2 dc) in corner sp; repeat from * 2 more times. Dc in each st and 2 dc in each ch-2 sp across the final side. Join with sl st to top of ch-3.
Per side: 2 corner dc + 15 dc (1 per st) + 12 dc (2 in each of 6 ch-2 sps) + 2 corner dc = 31 dc per side, including both corners’ 2 dc.
Stitch count: 124 dc, 4 ch-2 corner sps.
Check: 4 x 31 = 124. Each corner’s 4 dc split 2 and 2 between two sides, so nothing is counted twice.
Round 7 (Color A): Single Crochet Edge
Ch 1, sc in same st as join. *Sc in each dc to next corner, (sc, ch 2, sc) in corner sp; repeat from * 3 more times, working the final repeat around to the start. Join with sl st to first sc.
Stitch count: 124 sc (1 per existing dc) + 8 sc (2 added at each of 4 corners) = 132 sc, 4 ch-2 corner tips.
Per side: 33 sc, including 1 corner sc at each end.
Fasten off and weave in all ends.
Why the Math Works
Round 5 ends at 5 in (12.7 cm). At 16 dc = 3 in (7.6 cm), 31 dc span about 5.8 in (14.7 cm). The ch-2 corners add about 0.2 in (0.5 cm), giving 6 in (15.2 cm) per side.
Round 6 adds about 0.375 in (1.0 cm) on each side, and Round 7 adds about 0.125 in (0.3 cm). That makes 0.5 in (1.3 cm) per side, or 1 in (2.5 cm) total across the square: 5 in + 1 in = 6 in (15.2 cm).
Final Blocking
- Weave in all ends securely before blocking.
- Lightly mist the square with water until damp, not soaked.
- Lay it flat on a blocking mat.
- Pin the four corner tips first, with 6 in (15.2 cm) between neighboring corners.
- Check both diagonals. Each should measure about 8.5 in (21.6 cm).
- Pin the middle of each side so the edges are straight.
- Gently shape each puff petal with your fingers so the tips point outward.
- Open the cream lace arches and the treble corner fans with your fingertips.
- Let the square dry completely before unpinning.
Final Quality-Control Checklist
- Center hole is small and neat, about 0.25 in (0.6 cm).
- 8 blue petals, evenly spaced, all pointing outward.
- 8 cream V-shells sit between the petals.
- 16 cream clusters in 8 pairs.
- Round 5: 15 sts per side between corner ch-3 sps.
- Round 6: 31 dc per side, 124 dc total.
- Round 7: 33 sc per side, 132 sc total.
- All four sides measure 6 in (15.2 cm).
- Corners come to neat points.
- All ends are woven in and invisible from the front.
Troubleshooting
Petals look flat or thin: pull each puff loop to the full 0.75 in (1.9 cm) and keep the loops even before closing.
Center hole is too big: pull the magic ring tighter before joining Round 1, then secure the tail firmly.
Lace ring ruffles: your clusters are too loose. Tighten your tension or drop a hook size for Rounds 3-4.
Square cups in the middle: the cream rounds are too tight compared to the blue frame. Relax your tension on Rounds 3-4.
Corners curl or look rounded: check that each corner has a full (4 tr, ch 3, 4 tr) in Round 5 and (2 dc, ch 2, 2 dc) in Round 6.
Sides bow inward: recount Round 6. You should have exactly 31 dc per side.
Wrong count in Round 7: remember that each corner adds 2 sc, one on each side of the ch-2 tip.
Care
Hand wash in cool water with mild soap, press out excess water in a towel, and dry flat. Reshape and re-pin if needed.
Final Notes
The Frosted Bloom Granny Square follows a clear measurement chain. The flower reaches 2.5 in (6.4 cm) after Round 2, and the cream lace ring reaches 4.25 in (10.8 cm) after Round 4. The blue squaring round brings it to 5 in (12.7 cm) per side. The border adds 0.5 in (1.3 cm) on each side, for a finished 6 in (15.2 cm) square.
Check each stage against these numbers and keep your counts at 15, 31, and 33 stitches per side. Then the square will block cleanly every time.
Happy crocheting!
