A field of softly raised flowers gives this sea-glass crochet blanket its inviting texture. The reference suggests closely packed rosettes and gently uneven floral edges; this version builds that look with repeatable granny-square backings and sewn-on eight-petal flowers. A practical lap throw can rest on a sofa or wrap around your shoulders while reading. Choose a smooth, washable DK yarn so the petal texture remains distinct without making the blanket excessively heavy.

Before You Begin
This original construction is a written design draft, not physically test-crocheted. Check the target gauge and finished dimensions on a sample. Generated illustration collages show related floral-crochet ideas but may not depict every stated stitch or individual assembly operation exactly.
Work and measure one five-round square first, with its flower attached. The target is 12 × 12 cm (4.7 × 4.7 in) after gentle blocking, measured from outer corner to outer corner. A blocked 20 × 20 cm swatch of granny clusters is helpful for checking drape; the finished motif, rather than plain-stockinette-style stitch gauge, controls this modular design. Eight 12 cm squares give 96 cm across; ten give 120 cm along. Allow approximately 2 cm of edge on each side for a target 100 × 124 cm throw. Sizes are estimates until your own gauge is measured.
Each round is joined with a sl st; do not turn. Work with the RS facing. In square rounds, the starting ch 3 counts as the first dc. All other starting chains and all flower-petal ch 2 segments do not count as dc. The square's ch-2 corner spaces must remain accessible; do not mistake them for ch-1 side spaces. The flower uses all eight sc from its center, exactly one petal in each stitch. Fasten off leaving a long flower tail for attachment.
Complete Crochet Pattern
Step 1 — Make a granny-square backing (make 80)
Start with a magic ring, or ch 4 and sl st into the first chain to make a ring. A magic ring can loosen over time unless its tail is woven securely back through the center. The square grows outward from a four-corner foundation. At the beginning of later rounds, sl st into the next ch-2 corner space before working the first corner cluster. In a corner, (3 dc, ch 2, 3 dc) counts as two 3-dc groups with one corner space between them.
Ch 3 (counts as first dc), 2 dc into ring, ch 2; [3 dc into ring, ch 2] three times. Sl st to top of starting ch 3. Tighten the center after checking four groups.
(12 dc, 4 ch-2 corners)Sl st across to first corner. (Ch 3, 2 dc, ch 2, 3 dc) in that corner, ch 1; [(3 dc, ch 2, 3 dc) in next corner, ch 1] three times. Join to starting ch 3.
(24 dc, 4 ch-2 corners, 4 ch-1 side spaces)Start in first corner with (ch 3, 2 dc, ch 2, 3 dc), ch 1; work 3 dc in the next side ch-1 space, ch 1. Repeat that corner-to-corner sequence around, using (3 dc, ch 2, 3 dc) in each subsequent corner, and join.
(36 dc, 4 ch-2 corners, 8 ch-1 side spaces)Work a corner pair in each corner and 3 dc in each of the two side ch-1 spaces between corners. Separate neighboring groups with ch 1; join.
(48 dc, 4 ch-2 corners, 12 ch-1 side spaces)Work a corner pair in each corner and 3 dc in each of the three side ch-1 spaces between corners. Ch 1 between neighboring groups; join. Fasten off and weave in the backing tail.
(60 dc, 4 ch-2 corners, 16 ch-1 side spaces)The square has 3, 4, then 5 clusters along each side in rounds 3, 4, and 5 respectively, counting a cluster on each end corner. The whole round has 12, 16, and 20 three-dc groups respectively: 36, 48, and 60 dc.

Illustrative foundation sequence, reading the numbered views in order. For this written pattern: form the ring, make the four Round 1 clusters, fill each Round 2 corner, then add the Round 3 side groups; verify the stated counts instead of relying on the illustrative loop details.
Step 2 — Crochet the raised flower (make 80)
Use the same teal yarn and a 4.0 mm hook. The flower sits above the granny backing, and the petals remain free at their outer edges. This separate-appliqué method makes the construction countable and allows a maker to place each flower consistently. For a flatter flower, use 2 dc instead of 3 in each petal, but that is an optional alteration and will change the photographed texture.
Make a magic ring, ch 1 (does not count), work 8 sc into the ring, then sl st into first sc to join. Pull the ring closed but not so tightly that the stitches bunch.
(8 sc)In each of the eight sc in sequence work [sl st, ch 2, 3 dc, ch 2, sl st] all into that same sc. Do not skip or reuse center stitches. Fasten off leaving a 35 cm tail for sewing.
(8 petals; 24 dc total)One petal consumes one center sc and produces three dc, two short chain arches, and anchoring slip stitches. Eight original sc therefore create precisely eight petals. Gently open each petal with your fingers. Keep all 80 flower centers on the RS, and place each flower centrally over a square's ring, not over the corner spaces. Sew the center ring down now or after seaming all squares; the next section explains secure attachment. Measure your first decorated square before making 79 more. If the flower overwhelms its backing, try a smaller hook for the flower only.

Illustrative motif progression. In the drafted flower, the stages are: eight sc in an adjustable ring, make the first three-dc petal, anchor it in the same center stitch, repeat in successive stitches, and compare the final eight-petal disk against the square backing.
Step 3 — Arrange and join the floral squares
Arrange the 80 backing squares into 8 columns and 10 rows, all RS up, with granny corners aligned. Mark the top-left square and take a quick photograph for reference before moving pieces. This repeated modular layout forms a clear rectangle without trying to make the rosettes overlap at their bases. To retain the floral surface, attach flowers to each completed square before sewing rows together, leaving petal tips unattached.
Join squares WS together using a tapestry needle and matching yarn. For each neighboring pair, match the corners, then whipstitch through the outer loops of corresponding Round 5 edge stitches and the side-chain spaces. Make one seam stitch into each matching dc top and corresponding ch-1 gap. Do not pull the seam so tightly that the flowered faces cup. Join eight squares across to form one row; make ten rows. Join row 1 to row 2, then proceed down the length to row 10. The completed panel has 70 internal square-to-square joins within the ten rows (7 × 10) and 9 row-to-row seams across the full width. This is a seaming count, not the number of individual stitches.
Before adding the edging, the unbordered rectangle should be approximately 96 × 120 cm (37.8 × 47.2 in) at the assumed 12 cm square gauge. Compare opposite side lengths. If one side is shorter, check whether seams are puckering before blocking.
Step 4 — Add a simple matching border
With RS facing, join yarn at a blanket corner. Work a foundation edging of sc around the rectangle: 1 sc into each exposed dc and each ch-1 side space along the outer squares, placing an additional sc at every junction between two squares to cover the seam transition. Work 3 sc into each of the four outer corner ch-2 spaces. Join the round with sl st to its first sc; do not turn. On the eight-square edges, there are 19 exposed positions per square side (15 dc tops plus 4 side gaps), with seven internal square junctions; on the ten-square edges there are nine junctions. Working corners separately, this method yields 2 × (8 × 19 + 7) + 2 × (10 × 19 + 9) + 12 = 728 sc around the first border round. Check for evenness and adjust only if your joins occupy different spaces. For border round 2, ch 1 (not a stitch), sc once in each stitch around, making 3 sc in the middle stitch of each of the four corner increases instead of one; join and fasten off. This adds 8 stitches, for a nominal 736 sc in round 2. Block to the planned measurement; do not stretch the floral centers.

Illustrative assembly and edging sequence. Follow the written steps for lining up eight squares per row, sewing ten rows together, placing a sc edging around the perimeter, easing the corner increases, and preparing loose ends for weaving.
Assembly and Finishing
Center one flower on each of the 80 squares; thread its 35 cm tail through a needle and sew the ring securely to the backing's center ring with several small passes. For a little more stability, tack the base of every second petal to the first round of the backing, without pinning down the flower tips. Weave each yarn tail under at least five adjacent WS stitch backs, reverse direction, and make a second pass; trim after the fabric is gently stretched. Repeat for the joining and border tails. The flower petals should spring outward while the granny-square corners remain visible from the back.
Dampen with a spray bottle or wash according to the yarn label, then lay flat on a surface large enough for the full blanket. Shape the border into a rectangle measuring approximately 100 × 124 cm; distribute any extra ease rather than forcing petals open unnaturally. Let the textile dry completely before folding. The reference is visually dense and highly floral, but the real stitch density and drape will depend on fiber, hook, and tension.
Customization Ideas
Work the appliqué flowers one shade lighter than the backing squares. Keep yarn weight and hook unchanged; reassess yardage for each color.
Add two columns and two rows: 10 × 12 = 120 squares. At 12 cm each plus 4 cm of border, the approximate dimensions become 124 × 148 cm.
Sew down every second petal base instead of leaving all outer edges loose. Do not sew across the entire petal surface or the layered appearance disappears.
Use cream or muted sage for the two sc border rounds, leaving all 80 floral motifs in sea-glass teal.
Troubleshooting
Square corners curl upward
Possible cause: Tight corner chains or a hook that is too small
A motif has seven or nine petals
Possible cause: The first flower round did not contain eight sc, or one center stitch was reused
Joined rows ripple or pull inward
Possible cause: Whipstitches are too tight or edge gaps are mismatched
Border waves along the long edges
Possible cause: Extra sc inserted at seams or loose edge tension
Care Instructions
Cleaning
Check the exact yarn label before laundering. If machine washing is allowed, use a gentle cycle and a mesh bag for a sample or small section; otherwise wash the blanket carefully by hand in cool water.
Drying and reshaping
Press excess water out with towels rather than twisting petals. Lay flat, smooth seams, and allow it to dry completely away from strong heat.
Storage
Fold loosely on a shelf rather than hanging by an edge, which can stretch the open granny fabric and flower attachments.
