Hexagon layout: Crochet Blanket Layout Generator

Join whole flat-top hexagons without square-grid assumptions

This arrangement contains four staggered columns of five whole hexagons, twenty pieces in all. The entered twelve-centimeter size is point-to-point width, not a side length or flat-to-flat height. Each side is six centimeters, while the height is six times the square root of three centimeters. Adjacent column centers are nine centimeters apart horizontally. Odd columns sit half a hexagon height lower, creating actual shared sloping edges rather than square cells labeled as hexagons.

Count forty-three shared sides

Within each column, four neighbor pairs share horizontal sides, giving sixteen joins. Each of the three neighboring column pairs supplies nine sloping joins, adding twenty-seven. The total is forty-three shared sides and 258 centimeters of interior joining. Twenty hexagons have 120 sides before assembly. Removing two sides for each shared boundary leaves thirty-four exposed sides, a 204-centimeter stepped perimeter. These are whole-side counts, independent of each hexagon's crochet round count.

Read an envelope rather than a filled rectangle

The center's bounding width is thirty-nine centimeters. Its height is five and a half hexagon heights, approximately 57.16 centimeters. Those dimensions enclose notches around the outside; they do not describe a solid rectangular blanket area. The saved plan therefore reserves no rectangular border. Half-hexagon fillers, corner infill and a shaped border would need separately counted constructions before producing a straight-sided rectangle.

Questions and repair notes

Why are the yarn-role totals eight, six and six?

The finite staggered crop does not divide twenty pieces evenly among three roles. Use the numbered map rather than assuming a balanced count.

Can I enter twelve as flat-to-flat height?

That would be a different physical size. Convert the measurement first and confirm the tool's point-to-point label.

Why is my sloping join too long?

Check that you matched one six-centimeter side to one side, rather than treating the full twelve-centimeter tip span as an edge. Then compare actual edge insertion counts on a two-hexagon sample.

Exact settings and a counted motif trial

In the Crochet Blanket Layout Generator, select hexagon, 4 columns, 5 rows, a 12 cm point-to-point hexagon width and 0 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.

Complete measured assembly sequence

1. Choose and swatch separate flat-top hexagon motif patterns. Block to the measured sizes before joining: #1 hexagon, column 1, row 1, 12 × 10.39230485 cm, yarn slot 1; #2 hexagon, column 2, row 1, 12 × 10.39230485 cm, yarn slot 2; #3 hexagon, column 3, row 1, 12 × 10.39230485 cm, yarn slot 1; #4 hexagon, column 4, row 1, 12 × 10.39230485 cm, yarn slot 2; #5 hexagon, column 1, row 2, 12 × 10.39230485 cm, yarn slot 3; #6 hexagon, column 2, row 2, 12 × 10.39230485 cm, yarn slot 1; #7 hexagon, column 3, row 2, 12 × 10.39230485 cm, yarn slot 3; #8 hexagon, column 4, row 2, 12 × 10.39230485 cm, yarn slot 1; #9 hexagon, column 1, row 3, 12 × 10.39230485 cm, yarn slot 2; #10 hexagon, column 2, row 3, 12 × 10.39230485 cm, yarn slot 3; #11 hexagon, column 3, row 3, 12 × 10.39230485 cm, yarn slot 2; #12 hexagon, column 4, row 3, 12 × 10.39230485 cm, yarn slot 3; #13 hexagon, column 1, row 4, 12 × 10.39230485 cm, yarn slot 1; #14 hexagon, column 2, row 4, 12 × 10.39230485 cm, yarn slot 2; #15 hexagon, column 3, row 4, 12 × 10.39230485 cm, yarn slot 1; #16 hexagon, column 4, row 4, 12 × 10.39230485 cm, yarn slot 2; #17 hexagon, column 1, row 5, 12 × 10.39230485 cm, yarn slot 3; #18 hexagon, column 2, row 5, 12 × 10.39230485 cm, yarn slot 1; #19 hexagon, column 3, row 5, 12 × 10.39230485 cm, yarn slot 3; #20 hexagon, column 4, row 5, 12 × 10.39230485 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: 8; slot 2: 6; slot 3: 6. [20 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 (6 cm); #1 ↔ #5 (6 cm); #2 ↔ #7 (6 cm); #2 ↔ #6 (6 cm); #2 ↔ #5 (6 cm); #2 ↔ #3 (6 cm); #3 ↔ #4 (6 cm); #3 ↔ #7 (6 cm); #4 ↔ #8 (6 cm); #4 ↔ #7 (6 cm); #5 ↔ #6 (6 cm); #5 ↔ #9 (6 cm); #6 ↔ #11 (6 cm); #6 ↔ #10 (6 cm); #6 ↔ #9 (6 cm); #6 ↔ #7 (6 cm); #7 ↔ #8 (6 cm); #7 ↔ #11 (6 cm); #8 ↔ #12 (6 cm); #8 ↔ #11 (6 cm); #9 ↔ #10 (6 cm); #9 ↔ #13 (6 cm); #10 ↔ #15 (6 cm); #10 ↔ #14 (6 cm); #10 ↔ #13 (6 cm); #10 ↔ #11 (6 cm); #11 ↔ #12 (6 cm); #11 ↔ #15 (6 cm); #12 ↔ #16 (6 cm); #12 ↔ #15 (6 cm); #13 ↔ #14 (6 cm); #13 ↔ #17 (6 cm); #14 ↔ #19 (6 cm); #14 ↔ #18 (6 cm); #14 ↔ #17 (6 cm); #14 ↔ #15 (6 cm); #15 ↔ #16 (6 cm); #15 ↔ #19 (6 cm); #16 ↔ #20 (6 cm); #16 ↔ #19 (6 cm); #17 ↔ #18 (6 cm); #18 ↔ #19 (6 cm); #19 ↔ #20 (6 cm). The recorded endpoints in the saved layout are centimeter coordinates from the upper-left. Total interior join length is 258 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. [43 shared edge segments]
3. Weave seam tails on the reverse. Check the exposed boundary: 34 base edge segments, total length 204 cm before any border. The center envelope is 39 × 57.16 cm. The sides step around whole hexagons, with no half motifs or rectangular infill supplied. This envelope is not a filled rectangular area. Finish and wash according to the yarn instructions, then record actual dimensions. [34 exposed base edge segments]

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 (not counted), then repeat (dc, ch 2, dc) six times; sl st to first dc. [12 stitches or stated units]
2. Sl st to the first corner space. Ch 2 (not counted). Repeat six times: (dc, ch 2, dc) in corner space, then dc in every old dc along the side up to the next corner. Join to first dc. [24 stitches or stated units]
3. Sl st to the first corner space. Ch 2 (not counted). Repeat six times: (dc, ch 2, dc) in corner space, then dc in every old dc along the side up to the next corner. Join to first dc. [36 stitches or stated units]

Six corner spaces are maintained separately from dc counts. Each round adds 12 dc. Rotate the round start to a corner before continuing; block without stretching.
