This original nineteen-column, twenty-seven-row panel places a connected A-color diamond over the alternating-row ground of an overlay construction. Its logical drawing has seventeen interior columns and thirteen motif rows. Each logical row controls the drops in one B/A working pair. The two outer columns remain ordinary edge stitches. The design goal is understanding how a recognizable filled mark can emerge from long stitches while the underlying working yarn still changes only between complete rows.
Count the original logical shape
From the top, the marked widths are zero, one, five, seven, nine, thirteen, fifteen, thirteen, nine, seven, five, one and zero. They sum to eighty-five. The broadest mark leaves one unmarked logical column on either side, in addition to the two fixed edge columns. A mark is an instruction to make an A-color drop in the corresponding working pair, not an instruction to change yarn at that place in a B row.
Distinguish visible color from worked yarn
The complete rectangle contains 513 worked positions: 266 in A working rows and 247 in B working rows. Eighty-five A positions are long double crochets, replacing ordinary stitches at those positions. They also cover eighty-five B positions on the visible surface, so the finished chart shows 351 A-colored cells and 162 B-colored cells. The visible A count is not the number of A stitches made or a measured yarn allowance.
Keep the center from contracting
Use similarly weighted smooth yarns with a strong value difference. At the broad central area, spread the fabric to its relaxed width before drawing up each long stitch. A short drop can pull the previous B row upward, while an over-tight row-end attachment or mistaken turn changes the construction in a different way. Every row here begins again at the right edge. Keep row-end tails long enough for the finishing method you have actually sampled.
Questions and repairs
Why can I still see horizontal A lines outside the diamond?
Those are the ordinary A working rows. The ground is intentionally striped rather than a solid tapestry background.
Does eighty-five mean extra stitches?
No. Each drop replaces the ordinary stitch behind it. Every row remains nineteen positions wide.
Why is a diamond tip missing?
Compare the thirteen logical widths and their matching B/A pairs. Repair the first incorrect drop instead of adding another edge stitch.
Exact settings and complete working sequence
Choose diamonds, 19 chart columns and 27 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 13 rows. The saved operation count is 85 overlay dc and 428 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.
