How to Design a Seamless Pattern for All-Over Print

A seamless pattern is one square tile whose edges match, so it can repeat in every direction without a visible line. It is the easiest way to fill an all-over-print shirt, hoodie or pair of leggings, and it hides seams better than one giant image. Here is how to make one that prints well. Put it on a garment: all-over-print tee.

Step 1: Pick the motif

Choose two to five elements: an icon, a shape, a small illustration, your logo, a texture. More than that gets busy. Decide on three to five colors and stay with them. A limited palette is what makes a pattern look designed.

Step 2: Set the tile size

Work on a square canvas. Think about the printed size of one repeat on the garment: 3 to 6 inches is a good range for clothing. Make the tile at 300 pixels per inch at that size. For a 4-inch repeat, that is a 1200 by 1200 pixel tile. Bigger is fine. Smaller prints soft.

Step 3: Make the edges match

1. Place your elements in the middle of the tile, keeping them away from the edges.
2. Use your design app's offset tool to shift the tile by half its width and half its height. Most apps have this (in Photoshop it is Filter, Other, Offset). The old edges are now in the middle, and the old middle is at the corners.
3. Fill the empty middle with more elements. Do not touch the new edges.
4. Offset back if you want. The tile now repeats seamlessly.

In vector apps, the same idea works by copying any element that crosses an edge and placing the copy exactly one tile width or height away on the opposite side.

Step 4: Check the repeat

Tile it 3 by 3 on a bigger canvas and look for problems. Two things to watch: visible lines at the edges, and obvious rows or "stripes" where the same element lines up too neatly. Rotate, resize and nudge elements until the eye does not notice the grid.

Step 5: Test the scale on a garment

Put it in the builder on the actual garment. Patterns that look right on screen often look too small on a hoodie or too big on leggings. Adjust the scale until it reads from about six feet away.

Tips that save a reprint

• Keep a background color in the tile. Transparent areas can print as white.
• Avoid fine lines thinner than about 1 millimeter at print size.
• Use the same tile and scale on every piece of a set so they match. See matching workout sets.
• Keep text out of patterns. It gets cut off at seams and reads upside down on parts of the garment.

Is there really no minimum?

None. One piece is a real order at normal pricing, with no small-order surcharge and no setup or digitizing fee. Every piece is made to order and ships in about 5 to 9 business days, and that window is the same for one piece or a few hundred. On eligible garments, volume pricing applies automatically once you order enough of the same item, usually starting around 25 pieces.
