Letter blanket: C2C Graphgan Generator
A single original block letter
This sixteen-column, eighteen-row panel places a large teal S inside a cream margin. Its source is an explicitly defined five-by-seven block drawing, enlarged so every original mark becomes a two-by-two group of C2C blocks. No font file or third-party lettering chart is used. The goal is readable lettering with deliberate margins and a verified rectangular route, rather than a claim that the generator can automatically type any name or arrange a complete alphabet.
Count the letter and its margin
The small source S has three full five-cell bars and four single side cells, giving nineteen filled marks. Enlarging each mark to four blocks makes seventy-six teal blocks. The sixteen-by-eighteen canvas contains 288 blocks, leaving 212 cream blocks. Three cream columns remain on both sides and two cream rows above and below the enlarged letter. The route has thirty-three diagonals and 864 completed dc posts. These are construction counts; they are not the finished dimensions of a blanket or a measured yarn purchase.
Preserve the reading direction
Lay the source graph in its intended viewing orientation before working. The upper part of the S turns to one side while the lower part turns to the other; an unnoticed reflection can be difficult to diagnose once many tails have been woven. Start at the lower-left coordinate as instructed, not at the first teal block you recognize. The cream margin is worked fabric and must remain in the route. Keep the same coordinate convention when comparing the screen chart with a printed copy.
Work through the rectangular middle
This rectangle is taller than it is wide. Three central diagonals contain sixteen blocks each, but their starting-edge instructions are not interchangeable. Read the exact increase or decrease phase before starting every one. Equal block counts do not prove that the same side of the work is still growing. Use labelled supplies for separated cream areas and change yarn on the last pull-through before entering the next teal run. Count the two-block-thick bars against the source rather than trying to smooth their stepped edges.
Finish a usable letter panel
Measure several connected C2C blocks after finishing to estimate the physical size of the panel. If the intended blanket needs a different size, design a new whole-block layout with explicit margins rather than stretching or truncating the saved graph. After completing the last diagonal, check all three teal bars, the side connections and both cream side margins. Weave ends without narrowing the letter. Any seam, lining, border or additional letter panel belongs in a separately checked assembly plan.
Frequently asked questions and corrections
Can I type a different letter into this project?
The current C2C tool accepts a color grid, not an automatic text layout. Draw and count another original letter grid, then generate its own route.
Why are there seventy-six teal blocks rather than nineteen?
Nineteen describes the small drawing's filled marks. Each was enlarged to four crochet blocks, so the two counts refer to different units.
What if a central diagonal has the right total but the edge slopes outward?
Check the saved starting-edge phase. Correct the incorrect increase or decrease before continuing; the plateau does not authorize unlimited growth on both sides.
Actual parameters and yarn budget
Use 16 blocks across and 18 high in US terms. The exact palette is yarn 1: #EEE6D8 (212 blocks); yarn 2: #265D68 (76 blocks). These block totals describe the saved drawing, not yarn meters. A compatible block swatch is needed before estimating physical dimensions or material consumption.
Exact source and complete working instructions
Download this original graph as JSON and restore it in the C2C Graphgan Generator. Start with ch 6 and dc in the fourth, fifth and sixth chains from the hook. Each later block uses the written chain space, ch 3 and 3 dc; follow its coordinate and edge phase. In UK terminology these dc posts are tr. Read the chart-reading guide if the displayed picture and working route are unfamiliar.
Reverse the working direction once between successive diagonals. For an increase start, turn before making the new chain-six block. For a decrease start, the listed instruction already includes the turn; do not turn a second time. Follow the starting-edge action even when successive diagonals have equal block counts.
