About this design

What the design shows

The koi bends into a compact C, its head pointing left and slightly down while the body curls back toward the right. Two thin whiskers extend from the mouth, and dark patches sit around the eye and forehead. Rows of rounded scales cover the shoulder and body, shifting from pale centres to darker edges as they turn around the curve. A high dorsal fin rises above the back in a fan of ribbed rays. Below, the pectoral fin folds inward and the tail splits into two long, ragged-edged lobes that sweep left. Black and grey shading concentrates along the spine and lower body, with unfilled scale centres creating a patterned surface. Nothing surrounds the fish, so the open interior of the C remains visible. In the preview the koi spans the central upper back, about hand length, with the head near the left shoulder blade and tail falling diagonally down.

Placement

Placement and size

Across the upper back, the curved fish uses the space between the shoulder blades while its head and tail point in opposite directions. Its looping body also follows the outer thigh, shoulder cap, upper arm, or calf. Give the koi a hand-length area so individual scales, fin rays, and whiskers stay distinct. If it needs to be smaller, reduce the number of scale rows and make the tail divisions broader rather than compressing every line.

Patchwork

Building it into a patchwork

The koi carries medium-dark weight because its scale field is dense, yet the open center of its C keeps the silhouette from reading as a solid circle. It can anchor an upper-back composition or curve around a separate small symbol. A wave fragment, chrysanthemum, or short reed can echo its movement nearby. Keep other heavy blackwork away from the tail fringe and whiskers. A narrow skin gap around the dorsal fin gives the fish enough separation from neighboring pieces.
