Patterns are formed with repetition in one or more direction. This can be a hard geometrical repetition or soft implied repetition.
Working with patterns is an addiction. Hopefully there is a joy when you are working repetition.
Color can be used to tun the pattern in many directions. The emotional pull of color cannot be underestimated, from danger signals to childhood favorite colors.
The size of the printed pattern can push and pull the design in various directions. A simple pattern printed large can be intense, while a complicated pattern of many hues, saturations, and brightness levels printed small can visually fade into a single color.
Ancient technology of weaving textiles and basketry produce many patterns that we still use today. Likewise the production of microchips often include arrays of nearly identical items. Animals, plants, and fungi provide us with more patterns to observe and enjoy.
Modern fabric printing processes permit bold patterns to be created on a variety of textiles using pigment based inks. These can be found on my Spoonflower site. My current collection is Mid-Century Spectrum.
Cotton Canvas Pillows
Cotton-linen blend in two print sizes.
Twelve patterns in two sizes for each color. Each color has a pattern variation different than the other colors.

A watery view of colors formed with a random array of transparent ovals.

Layers of stars in blue hues form a field of frost.

Stripes created in a desert growth spectrum.

Further work on texture with random stripe with and spots of additional tones.

Transparent rectangles with highlight spots to pop through the layers.

Deeper tones of violet and blue.

Transparent squares with pinpoints of light on a dark background.

Simple matrix of squares in analogous colors.

Four point stars atop the matrix of squares.

The addition of circles within the squares along with the four point stars.

Switching to sharper stars.

Experiment with intermediate curves. Pattern is useful for creating variations in surface texture.

Intermediate curves in color.

Intermediate curves and triangles creates a regatta.

Bright pattern with starts, circles, squares, and triangles.

Hearts and dots added to the stars, squares, circles, and triangles. This image was created in an analogous spectrum centered on blue green.

The yellow orange corner of the color wheel is highlighted in this pattern.

The split complementary scheme centered on blue green pops in this pattern.
