Symmetric panel: C2C Graphgan Generator

A frame and a centered medallion

The original twelve-by-twelve panel separates an outside navy frame from an amber diamond in a cream interior. Its main design question is how to verify two reflection axes and count a border without double-counting corners. It is useful as a compact alignment study before joining a central motif to other panels. The navy frame is already part of this color graph; it is not a separately crocheted blanket edging.

Two independent area calculations

The outside frame contains forty-four blocks. Count twelve along the top and twelve along the bottom, then ten along each side between them: the corner cells must not be counted twice. The centered diamond contains twenty-four amber blocks, and the remaining seventy-six cells are cream. Together those totals make 144. There are twenty-three diagonal working steps and 432 completed dc posts. The center lies between four cells because twelve is even; do not force a single central stitch into a drawing designed around a shared midpoint.

Use symmetry as an error check

Reflect the matrix left to right and top to bottom before working. Both operations should retain every color. Count corresponding cells on opposite sides of the center when checking the amber shape. A correct total of twenty-four amber blocks is insufficient if one has moved to the wrong side. The explicit lower-left coordinate convention still matters, even though this particular symmetric image can conceal a vertical reversal visually. Keep the convention consistent when later combining it with an asymmetric panel.

Work the frame as ordinary C2C fabric

The starting cell is navy, but the early diagonals soon meet cream. Follow the saved colors and working phases without treating the frame as a separate strip to attach later. At an outside edge, count only the blocks required for that diagonal before turning or beginning the next one. Maintain even tension where the short navy runs meet the pale interior. Separate supplies can reduce dark strands showing through the cream back, especially near the corners.

Prepare for joining

Finish and measure a connected-block trial before assigning a physical size to the twelve-block edge. After completing the graph, inspect all four corners and the centered medallion before weaving tails permanently. If the panel is one part of a larger design, compare its actual edge with the neighboring fabric and choose a compatible seam. A further outside border adds new work and needs its own count budget. Do not describe the existing navy color frame as a calculation for that extra border.

FAQ and correction methods

Why is there no single center cell?

An even-width grid has its center between columns and rows. The four-cell central relationship is intentional rather than a missing position.

Does a matching color total prove symmetry?

No. Compare reflected coordinates as well as totals. Two displaced amber blocks can preserve the area while breaking the drawing.

Can I add a contrasting edging?

Yes as a separately specified construction after measuring the finished edge. It is not generated by changing the navy frame's color.

Actual parameters and yarn budget

Use 12 blocks across and 12 high in US terms. The exact palette is yarn 1: #F5EBDD (76 blocks); yarn 2: #243A57 (44 blocks); yarn 3: #C88B28 (24 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.
