Here are some ways to combine two colors in a quilt pattern, ranging from simple to complex:

Basic Block Variations:

• Alternating Squares: The simplest approach. Arrange squares of each color in an alternating grid pattern. Variations include changing the size of the squares (e.g., a 2x2 grid of larger squares alternating with a 4x4 grid of smaller squares).

• Checkerboard: A classic pattern using equal-sized squares of each color arranged in a checkerboard pattern.

• Stripes: Use horizontal, vertical, or diagonal stripes of each color. Vary the stripe width for different effects. Consider using bias stripes for a more dynamic look.

• Half-Square Triangles (HSTs): Sew squares of each color together, cut them diagonally, and arrange the resulting triangles to create various patterns. This allows for intricate designs even with only two colors. Consider using different sizes of HSTs.

• Quarter-Square Triangles (QSTs): Similar to HSTs, but you cut the squares into four triangles. This opens up even more design possibilities.

More Complex Block Variations:

• Log Cabin: Start with a small square of one color in the center and add progressively larger strips of the other color around it, creating a log cabin effect. You can vary the order and width of the strips.

• Ohio Star: This block uses a star shape created by piecing together squares and triangles of both colors. Variations in the size and arrangement of the pieces create different looks.

• Pinwheel: This pattern uses squares and triangles arranged to create a pinwheel effect. The colors can be arranged to emphasize the pinwheel or create a more subtle effect.

• Flying Geese: This block uses triangles of one color set against a background of the other color, creating a pattern that resembles flying geese. Variations in the size and arrangement of the geese create different looks.

• Rail Fence: This pattern uses strips of each color sewn together to create a fence-like effect. Variations include changing the width of the strips and the direction of the fence.

Beyond Individual Blocks:

• Block-on-Point: Rotate blocks to create a different visual effect. This can significantly change the look of even simple blocks.

• Setting Triangles: Use triangles of one or both colors to create a border or to connect blocks in interesting ways.

• Sashes: Use strips of one color to separate blocks of the other color. This can create a more structured and organized look.

Remember to consider the scale of the pattern. Larger blocks will create a bolder look, while smaller blocks will create a more intricate design. Experiment with different arrangements and sizes to find the perfect combination for your quilt. Sketching your ideas beforehand can be very helpful.
