Rainbow blocks: Crochet Blanket Layout Generator

Shift the rainbow by one block per row

The rainbow arrangement has six columns, five rows and six yarn slots. The first row runs through slots one to six; every following row begins one slot later and wraps at the end. Each row therefore contains all six colors once, so the complete thirty-block plan uses five blocks in every slot. Its diagonal flow comes from actual row phase shifts, rather than a vertical stack of identical rainbow stripes.

Keep wraparound visible in your labels

A slot-six block can sit beside a slot-one block at a phase boundary. That is an intended cyclic transition. Number the pieces before joining, and compare the first and last blocks of each row with the saved map rather than sorting finished squares into six independent color piles and improvising the order. A misplaced block may preserve the total quantity of every yarn role while breaking the diagonal sequence.

Use thirty pieces and forty-nine joins

Five shared vertical boundaries in each of five rows contribute twenty-five segments. Four horizontal boundaries in each of six columns add twenty-four. At the assumed ten-centimeter blocked side, the forty-nine joins total 490 centimeters. The center is sixty by fifty centimeters, with an outside perimeter of 220 centimeters. A nominal two-centimeter border would give sixty-four by fifty-four centimeters, subject to the actual seam and border measurements.

Questions and practical fixes

Does five blocks per color imply equal yarn weights?

Only if the actual block construction and yarn consumption match. Different fibers, motifs or multi-color centers need measured material budgets.

Can I reverse the entire rainbow?

Reorder the palette and save a new project while preserving the slot rule. Reversing only one row changes its relationship with both neighbors.

Why does my diagonal stop at the edge?

The finite rectangle wraps the six-slot sequence. Check the next row's starting slot rather than adding an unplanned seventh column.

Is a rainbow photo required to use the plan?

No. The downloadable counted layout and the separately crocheted square sample provide the working references; the color swatches represent entered yarn roles.

Exact settings and a counted motif trial

In the Crochet Blanket Layout Generator, select rainbow, 6 columns, 5 rows, a 10 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.

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: 5; slot 3: 5; slot 4: 5; slot 5: 5; slot 6: 5. [30 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 (10 cm); #1 ↔ #7 (10 cm); #2 ↔ #3 (10 cm); #2 ↔ #8 (10 cm); #3 ↔ #4 (10 cm); #3 ↔ #9 (10 cm); #4 ↔ #5 (10 cm); #4 ↔ #10 (10 cm); #5 ↔ #6 (10 cm); #5 ↔ #11 (10 cm); #6 ↔ #12 (10 cm); #7 ↔ #8 (10 cm); #7 ↔ #13 (10 cm); #8 ↔ #9 (10 cm); #8 ↔ #14 (10 cm); #9 ↔ #10 (10 cm); #9 ↔ #15 (10 cm); #10 ↔ #11 (10 cm); #10 ↔ #16 (10 cm); #11 ↔ #12 (10 cm); #11 ↔ #17 (10 cm); #12 ↔ #18 (10 cm); #13 ↔ #14 (10 cm); #13 ↔ #19 (10 cm); #14 ↔ #15 (10 cm); #14 ↔ #20 (10 cm); #15 ↔ #16 (10 cm); #15 ↔ #21 (10 cm); #16 ↔ #17 (10 cm); #16 ↔ #22 (10 cm); #17 ↔ #18 (10 cm); #17 ↔ #23 (10 cm); #18 ↔ #24 (10 cm); #19 ↔ #20 (10 cm); #19 ↔ #25 (10 cm); #20 ↔ #21 (10 cm); #20 ↔ #26 (10 cm); #21 ↔ #22 (10 cm); #21 ↔ #27 (10 cm); #22 ↔ #23 (10 cm); #22 ↔ #28 (10 cm); #23 ↔ #24 (10 cm); #23 ↔ #29 (10 cm); #24 ↔ #30 (10 cm); #25 ↔ #26 (10 cm); #26 ↔ #27 (10 cm); #27 ↔ #28 (10 cm); #28 ↔ #29 (10 cm); #29 ↔ #30 (10 cm). The recorded endpoints in the saved layout are centimeter coordinates from the upper-left. Total interior join length is 490 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. [49 shared edge segments]
  3. Weave seam tails on the reverse. Check the exposed boundary: 22 base edge segments, total length 220 cm before any border. The center envelope is 60 × 50 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. [22 exposed base edge segments]
  4. Plan a nominal 2 cm border outside each edge of the measured rectangular center. The geometric estimate is 64 × 54 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.
