The eighteen-column, thirty-three-row panel contains a sixteen-by-sixteen logical interior. Four eight-square tiles fill that interior. In each tile, the marked cells widen from one at the top to eight at the bottom, making an original right-triangle arrangement. The goal is keeping repeated geometry complete while translating its marks into a mechanically valid overlay sequence with fixed single-crochet edges.
Verify tile area before stitching
One eight-row triangle contains one plus two plus three through eight marks, thirty-six in total. Four tiles therefore require 144 drops. The full working rectangle has 594 positions. A uses 306 of those working positions and B uses 288. After the long A stitches cover earlier B positions, the surface shows 450 A-colored cells and 144 B-colored cells. The visible B total happens to equal the drop count here, but those are different sets and should not be treated as a general rule.
Work across a tile boundary without adding an edge
The two tiles across a logical row meet inside one continuous crochet row. No standing stitch, joining slip or extra chain is inserted between them. Only the outside left and right columns use the fixed edge treatment. Count the interior runs against the complete row rather than fastening off at a triangle's visual boundary. When the second set of logical tiles begins, the triangular width returns to its one-mark phase by design.
Keep the background as ordinary overlay fabric
Unmarked logical cells do not become holes. They preserve the normal striped A/B ground by using an ordinary A stitch rather than a covering drop. Make a small finished sample with clear yarn contrast and compare both the wide bottom of a triangle and its narrow top. Long stitches that are pulled too tight can bend a diagonal despite correct coordinates. Correct tension without moving the source marks or changing row width.
Questions and repair choices
Are these four separately crocheted triangles?
No. They are four pictorial tiles within one rectangular fabric. There are no triangle seams.
Why does a tile start wide?
Compare the top-to-bottom logical drawing with the bottom-origin working order. The saved route begins at the lower edge of the complete panel.
Can I remove the striped background?
That changes the construction. A solid-color pictorial background belongs in another counted method rather than an unrecorded omission of rows.
Exact settings and complete working sequence
Choose triangles, 18 chart columns and 33 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 16 columns by 16 rows. The saved operation count is 144 overlay dc and 450 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.
