Quick answer

## The short version

Check spacing, orientation and perspective in repeated backgrounds. Tiles, bricks and wallpaper give the viewer strong clues when an extension drifts out of alignment.

## A capture or editing plan

Identify the pattern's repeat and any perspective direction in the source. Compare an extended result with guide lines through several existing rows, not only the row nearest the join. Inspect whether individual motifs change size or merge. For a graphic pattern you own, extending the real pattern in a conventional editor may provide more control than generating an approximation.

## When to change the approach

Use a real pattern extension when exact repetition matters, such as a catalog image of a material. A generated repeat is unsuitable as evidence of the product's actual design.

## Worked planning example

Planning example: A checkerboard floor is extended to the right. The new squares gradually become narrower than the source rows, revealing a perspective mismatch that is visible even though each individual square looks tidy.

## If the first attempt fails

If the pattern continues at one edge but drifts farther out, count the spacing between several repeated elements. A single clean join does not establish consistent scale across the added area. Check any apparent writing or logos separately because repetition can turn into invented characters. A plain designed margin may be preferable when exact wallpaper, fabric or tile geometry is important to the image's purpose.

## Before you finish

1. Follow more than one repeated row.
2. Check motif scale and perspective.
3. Prefer real pattern data when accuracy matters.
