This nineteen-column, thirty-five-row study uses an original seventeen-square logical tile. Selected vertical bands and selected horizontal bands each occupy seven positions along their respective axes. A logical cell is marked only when it lies in exactly one of those band sets. Their intersections remain unmarked. The goal is testing a symmetric negative-space arrangement rather than simply overlaying two filled crosses and counting the overlap twice.
Derive the foreground area independently
Seven selected x positions paired with ten unselected y positions produce seventy marks. Ten unselected x positions paired with seven selected y positions produce another seventy. The sets do not overlap, giving 140 drops. The 665 working positions comprise 342 in A and 323 in B. After covering 140 B positions, the visible chart has 482 A-colored cells and 183 B-colored cells.
Inspect both reflection axes
The logical drawing must reproduce itself when reflected horizontally or vertically. The center belongs to both selected bands and is therefore deliberately unmarked. That central ground is not a missing connection in the fabric. Compare the four quadrants and the band intersections before starting, then use the exact working route rather than trying to crochet each quadrant separately. Every complete row uses one yarn from right to left.
Preserve the texture through a band change
Eighty-two drops in the saved execution use available front loops of earlier A double crochets. Other drops begin in A single crochets. Both use the specified two-row reach and leave the output width unchanged. At a change from a marked band to an unmarked region, resume ordinary A stitching where instructed. Continuing the drop merely because the previous rows formed a column would fill an intended negative-space interval.
Questions and common mistakes
Why is the center striped?
The two selected band sets intersect there, so the exclusive rule leaves it unmarked and preserves the ordinary ground.
Can I mirror each working row manually?
No. The source already has its intended symmetry, and every physical row is worked right to left. Manual reversal is unnecessary and can change coordinates.
Does symmetry prove flatness?
No. It proves a property of the logical drawing. Finish a real trial to assess gauge, drop tension and relaxed fabric behavior.
Exact settings and complete working sequence
Choose symmetric-tile, 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 140 overlay dc and 525 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.
