Ombre Quilt Block Tutorial: Easy 10" Diamond Design with Stunning Color Gradation

By: Elaine Huff

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)

Corner Units:

Step 4:

Make four Corner units using the Step 3 units, and eight of the Dark 2.5" squares. This unit goes together just like a partial Snowball block except that you use the Half Square Triangle unit for the base. You can find my tutorial for making a Snowball block at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-snowball-block

Here are the first steps, going from left to right: 
  • 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)
  • Refold. (right image, bottom right corner)

Step 5:

Repeat Step 4 for a total of four Corner units as shown below.

Two-Patch Units:

Sew one of the Light 2.5" square to a Medium 2.5" square and press the seam allowance away from the Medium square as shown in the bottom right image below. Repeat for a total of four units.
 

Putting It All Together:

Step 7:

Lay out the Corner units, the Two-Patch units, and the remaining Dark 2.5" square as shown in the picture below.

Layout Ideas:

Here's the basic 4 x 4 layout using colors similar to the tutorial. You get a lovely secondary diamond design.
 
quilt 1
This is the same layout as above but with 1.5" sashing and cornerstones added. 
 
quilt 2
This is what a scrappy layout could look like.
 
quilt 3
This is an alternating layout where every other block is a modification of the main block. The modification was to turn the center octagon shape of the block into one color. 
 
quilt 4
In this alternating layout, a modified main block that makes a cross design was used for the alternate block. I also switched up the light, medium, and dark placement of colors in both blocks.
 
quilt 5
This is an on-point layout where the block extends into the setting triangles. 
 
quilt 6
This is an alternating on-point layout using a modified main block for the alternate block. What a difference!

Conclusion:

I had a lot of fun with the Ombre block! It went together quickly and easily which was nice. At first I didn't expect to get many layout options out the block but was pleasantly surprized with how versatile it is!
