Ombre Quilt Block Tutorial: Easy 10" Diamond Design with Stunning Color Gradation
The Ombre quilt block is a fresh, modern take on a classic diamond design, finishing at 10" and coming together with simple, beginner-friendly piecing. Traditionally made with light, medium, and dark shades of a single color, this block creates a beautiful sense of depth and movement as the values shift across the diamond.
Whether you carefully plan a smooth color gradation or pull from your scrap bin for a more playful look, the Ombre block is an easy and satisfying make that really shines when multiple blocks are sewn together.

Fabric Requirements for a 10" Finished Ombre Quilt Block:
- Light: 2 - 5" squares, and 4 - 2.5" squares
- Medium: 2 - 5" squares, and 4 - 2.5" squares
- Dark: 9 - 2.5" squares

Sewing Directions:
Half Square Triangle Units:
Step 1:
Using a Light 5" square and a Medium 5" square, make Half Square Triangle (HST) units as shown.
- Match up a Light square and a Medium square right sides together. Mark a diagonal line from corner to corner on the back of the White square and sew 1/4" (or a little less) on each side of the line (left image).
- Cut along the diagonal line. You will have 2 half-square triangle patches. (right image)

Step 2:
- Open up the patch and press the seam allowance toward the Medium fabric.
- Square up/trim the units to 4.5" square.
- You can find my tutorial for making HST units at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-half-square-triangle-block

Step 3:

Corner Units:
Step 4:
- Mark a diagonal line from corner to corner on the back of the 2.5" squares. Sew a 2.5" square to opposite corners of the Step 3 unit along the marked line. Note the orientation of the marked line. (left image, top left corner)
- Match the corners of the 2.5" square and press. (left image, bottom right corner)
- Open up the 2.5" square and trim the seam allowance. (right image, top left corner)
