How to make a seamless repeat
Drop a motif onto the box, choose a file or paste an image, and the tile is rebuilt as you change any setting. A motif can be a single object on a transparent background, such as a flower cut out in a drawing app, or a finished square of artwork. With Trim empty edges on, transparent margins are cropped so spacing is measured from the motif itself.
The four repeat types
- Full drop (block): motifs sit in a straight grid, side by side and directly above one another. The tile is one cell.
- Half drop: every second column slides down by half a cell, so motifs line up on the diagonal and the grid is harder to spot. The tile is two cells wide; a third or quarter drop makes it three or four cells wide.
- Brick: the same idea turned sideways. Every second row shifts across by half a cell, like brickwork, and the tile is two cells tall.
- Mirror: the motif is reflected left to right and top to bottom, giving four versions in a 2 × 2 tile.
The other settings
Scale is a percentage of the image you dropped. Space across and Space down add room between motifs as a share of the motif's size; negative values make neighbours overlap. Rotation turns every motif. Offset moves the motif within its cell, which changes where the tile's edges fall but not how the pattern looks. Seam check cuts the tile in half both ways and swaps the pieces, so the old edges cross in the middle along the dashed lines: any break there would show as a line on fabric.
Example: the peacock plume sample is 448 × 770 px. At 60% it becomes 269 × 462 px; with 20% space across and 10% down each cell is 323 × 508 px, so the half-drop tile is 646 × 508 px and holds two plumes. At 150 DPI one repeat prints 4.31 × 3.39 in (10.94 × 8.6 cm).
