Sunburst blanket: Crochet Blanket Layout Generator

Arrange sunburst blocks in a diamond-distance field

This five-by-five plan places a chosen center block in the middle of twenty-five whole squares. A block's yarn role follows its horizontal distance plus vertical distance from that center, cycling through four slots. The result has diamond-shaped color bands in a square envelope. This arrangement rule is separate from the round-by-round stitch structure inside a Sunburst square. The companion project supplies the latter; the layout supplies the former.

Count rings and the four far corners

Distance zero contains one block, distance one four, distance two eight, distance three eight and distance four four. Cycling four slots sends those four far corners back to slot one, along with the center. The final totals are five, four, eight and eight. Count that wrap explicitly before purchasing yarn or mistaking the corner color for a broken ring. The layout is reflected across both center axes because it has an odd number of rows and columns.

Plan joins independently of motif rounds

Twenty horizontal and twenty vertical unit boundaries make forty joins. At an assumed twelve-centimeter blocked side, the total interior seam is 480 centimeters and the center is sixty centimeters square. A nominal two-centimeter border gives a sixty-four-centimeter square estimate. The number of puff or cluster rounds inside a Sunburst block does not enter that seam formula. Its actual edge posts, corner spaces and blocked size do determine whether corresponding motifs can be joined without gathering.

FAQ and likely mistakes

Why does slot one appear in both center and corners?

The distance rule cycles after four. Distance four has the same palette role as distance zero.

Can I use an even-width layout?

The generator chooses a particular center cell. With an even count there is no single geometric middle block, so the same rule is not perfectly centered in the envelope.

Does the layout choose inner Sunburst colors?

No. Record those separately in each motif recipe. The map's role can identify a dominant outside color while the center and puff-ring yarns follow their own saved assignment.

Exact settings and a counted motif trial

In the Crochet Blanket Layout Generator, select sunburst, 5 columns, 5 rows, a 12 cm base square side and 2 cm nominal border. These are a measured planning assumption, not a claim that the example yarn has been physically sampled. Use smooth compatible yarns, a matching hook, a tapestry needle and removable labels. Download the exact layout JSON before changing size or palette.

The separate counted motif below is an original reproducible construction for a trial. Make and finish it in the intended yarn, wash and block according to the yarn instructions, and measure its resting dimensions. Only use the stated layout size if the real sample matches; otherwise update the measured plan or adjust the motif through a new swatch. A slot in this layout identifies a whole motif's dominant yarn role. Recolor the trial consistently for each role; detailed multicolor flower rounds need their own saved palette. US and UK modes preserve all geometry. Follow the joining guide and test corresponding edge insertions before making the complete set.

1. Choose and swatch separate square motif patterns. Block to the measured sizes before joining: #1 square, column 1, row 1, 12 × 12 cm, yarn slot 1; #2 square, column 2, row 1, 12 × 12 cm, yarn slot 4; #3 square, column 3, row 1, 12 × 12 cm, yarn slot 3; #4 square, column 4, row 1, 12 × 12 cm, yarn slot 4; #5 square, column 5, row 1, 12 × 12 cm, yarn slot 1; #6 square, column 1, row 2, 12 × 12 cm, yarn slot 4; #7 square, column 2, row 2, 12 × 12 cm, yarn slot 3; #8 square, column 3, row 2, 12 × 12 cm, yarn slot 2; #9 square, column 4, row 2, 12 × 12 cm, yarn slot 3; #10 square, column 5, row 2, 12 × 12 cm, yarn slot 4; #11 square, column 1, row 3, 12 × 12 cm, yarn slot 3; #12 square, column 2, row 3, 12 × 12 cm, yarn slot 2; #13 square, column 3, row 3, 12 × 12 cm, yarn slot 1; #14 square, column 4, row 3, 12 × 12 cm, yarn slot 2; #15 square, column 5, row 3, 12 × 12 cm, yarn slot 3; #16 square, column 1, row 4, 12 × 12 cm, yarn slot 4; #17 square, column 2, row 4, 12 × 12 cm, yarn slot 3; #18 square, column 3, row 4, 12 × 12 cm, yarn slot 2; #19 square, column 4, row 4, 12 × 12 cm, yarn slot 3; #20 square, column 5, row 4, 12 × 12 cm, yarn slot 4; #21 square, column 1, row 5, 12 × 12 cm, yarn slot 1; #22 square, column 2, row 5, 12 × 12 cm, yarn slot 4; #23 square, column 3, row 5, 12 × 12 cm, yarn slot 3; #24 square, column 4, row 5, 12 × 12 cm, yarn slot 4; #25 square, column 5, row 5, 12 × 12 cm, yarn slot 1. Match corresponding edge stitches or spaces on a two-piece seam trial; centimeters alone do not establish compatible insertion counts. Color totals: slot 1: 5; slot 2: 4; slot 3: 8; slot 4: 8. [25 separate motifs]
2. Lay out the numbered pieces with the face up as in the map. Sew or slip-stitch the following pairwise edges once each, without tightening the fabric: #1 ↔ #2 (12 cm); #1 ↔ #6 (12 cm); #2 ↔ #3 (12 cm); #2 ↔ #7 (12 cm); #3 ↔ #4 (12 cm); #3 ↔ #8 (12 cm); #4 ↔ #5 (12 cm); #4 ↔ #9 (12 cm); #5 ↔ #10 (12 cm); #6 ↔ #7 (12 cm); #6 ↔ #11 (12 cm); #7 ↔ #8 (12 cm); #7 ↔ #12 (12 cm); #8 ↔ #9 (12 cm); #8 ↔ #13 (12 cm); #9 ↔ #10 (12 cm); #9 ↔ #14 (12 cm); #10 ↔ #15 (12 cm); #11 ↔ #12 (12 cm); #11 ↔ #16 (12 cm); #12 ↔ #13 (12 cm); #12 ↔ #17 (12 cm); #13 ↔ #14 (12 cm); #13 ↔ #18 (12 cm); #14 ↔ #15 (12 cm); #14 ↔ #19 (12 cm); #15 ↔ #20 (12 cm); #16 ↔ #17 (12 cm); #16 ↔ #21 (12 cm); #17 ↔ #18 (12 cm); #17 ↔ #22 (12 cm); #18 ↔ #19 (12 cm); #18 ↔ #23 (12 cm); #19 ↔ #20 (12 cm); #19 ↔ #24 (12 cm); #20 ↔ #25 (12 cm); #21 ↔ #22 (12 cm); #22 ↔ #23 (12 cm); #23 ↔ #24 (12 cm); #24 ↔ #25 (12 cm). The recorded endpoints in the saved layout are centimeter coordinates from the upper-left. Total interior join length is 480 cm. At a T-junction, match the marked midpoint of the large edge to the meeting small-block corners; do not force one small edge to cover the whole large side. [40 shared edge segments]
3. Weave seam tails on the reverse. Check the exposed boundary: 20 base edge segments, total length 240 cm before any border. The center envelope is 60 × 60 cm. Recheck both diagonals and measure the relaxed joined rectangle before planning border stitch counts. Finish and wash according to the yarn instructions, then record actual dimensions. [20 exposed base edge segments]
4. Plan a nominal 2 cm border outside each edge of the measured rectangular center. The geometric estimate is 64 × 64 cm. Swatch the border separately, derive pickup and corner stitch counts from the actual joined edges and measure its finished width. This layout supplies no universal border round count or guaranteed gauge. [4 planned rectangle corners]

Representative motif: complete counted construction

Open the corresponding motif tool and restore the exact motif project. Its stitch counts are construction data; they do not certify the assumed centimeter size. Make the required copies and recolor by the layout's role totals.

1. Magic ring: ch 2 (does not count), 16 dc; sl st to first dc. Tighten ring. [16 stitches or stated units]
2. Join puff color. In each dc make one puff: [yarn over, insert hook and pull up a loop] three times; yarn over and pull through all 7 loops; ch 1 to secure, then ch 1 for spacing. Join to first puff. 16 puffs and 16 spacing gaps. [16 stitches or stated units]
3. In each spacing gap work a 4-dc cluster, ch 2. Cluster: [yarn over, insert into gap, pull up loop, yarn over, pull through 2] four times; yarn over and pull through all 5 loops. Join. 16 clusters and 16 ch-2 spaces. [16 stitches or stated units]
4. Join in a ch-2 space. Repeat four times: (3 tr, ch 2, 3 tr) in corner space; 3 dc in next space, 3 hdc in next, 3 dc in next. Join to first tr. Ch 3 to begin (not counted). 24 tr, 24 dc, 12 hdc; four corner spaces. [60 stitches or stated units]

Counts distinguish completed clusters/puffs from their partial posts. Corner chains are excluded from post count. This Sunburst center uses its stated puff/cluster construction; test flatness with the chosen yarn and hook.
