This nineteen-column, thirty-five-row panel contains three original logical diamond outlines inside a seventeen-square interior. The rings use Manhattan distances of two, five and eight from the central cell. The teaching goal is separating nested contours without filling their centers or joining them with unintended drop stitches. The complete physical fabric remains rectangular even though the logical foreground consists of three diamond rings.
Count outlines without filling the diamonds
A nonzero Manhattan-distance ring of radius r contains four times r cells. The three rings therefore contribute eight, twenty and thirty-two marks, sixty altogether. The saved pattern makes sixty A-color overlay double crochets across 665 working positions. Its A working rows use 342 positions and B rows 323. The completed surface contains 402 A-colored cells and 263 B-colored cells after the sixty covered B positions are accounted for.
Understand why these anchors differ from a stripe
Unlike the continuous-column study, this particular mask has no drops anchored into earlier double crochets. Every marked position reaches an available A single-crochet front loop. The gaps between ring contours prevent immediately successive logical marks in the same column. That is a property of this original mask, not a universal rule that every valid named design must use only single-crochet anchors.
Keep negative space as worked ground
The area inside a ring and the gaps between rings retain ordinary A/B stripes. They are not omitted stitches, open diamond holes or separate pieces to cut out. Work each full row from the right edge and compare the next drop against the intended ring radius. A stray mark between radii two and five can connect two outlines visually while preserving the total row width. Correct the mark rather than changing the edge count.
FAQ and useful checks
Why is the middle ring filled?
Compare the saved mask with distance five only. A less-than comparison would fill an area instead of drawing the prescribed outline.
Can I count the three filled diamond areas?
Those are different sets. This design counts ring cells, with no shared cells between the three selected distances.
How do I assess the physical shape?
Finish a representative overlay sample and measure stitch and row gauge. Two working rows per logical row affect proportions, so the digital diamond does not promise equal centimeter diagonals.
Exact settings and complete working sequence
Choose nested-diamonds, 19 chart columns and 35 physical working rows in the Mosaic Crochet Pattern Generator. Yarn A is #1B5462 and yarn B is #E7DAC0. Use smooth compatible yarns and a suitable sample hook. The logical interior is 17 columns by 17 rows. The saved operation count is 60 overlay dc and 605 ordinary sc, with all row-end tails separate from those counts.
Download the exact original mosaic project JSON. Restore it before comparing another palette or size. In US terms, ordinary interior stitches are BLO sc and the covering stitch is dc into an unused same-color front loop two rows below. In UK terms these are BLO dc and tr. Every drop replaces the ordinary stitch behind it. Begin with the stated chain foundation, attach each later row at the right, keep the front facing and cut at the left without turning. Secure the final tails after completing the last row; any border is separate. Read the chart-reading guide to distinguish working symbols from the final visible-color panel.
