How To Sash A Quilt + 15 Quilt Sashing Ideas

Have you ever created a few quilt blocks and thought, “These just need a little something extra, but what?” 

I know I have, and one of my favorite things to do is add sashing to my quilt blocks. 

In this post, I’ll teach you why sashing can be helpful and how to add it to your quilts. 

Finally, we’ll check out some beautiful examples of how other quilters have added sashing to their quilts for an extra design element. 

What Is Quilt Sashing and Why Do You Need It?

Quilt sashing is the borders added between quilt blocks in some quilt pattern designs. Sashing can be as wide or as narrow as you would like and can add a lot of visual interest to a quilt. 

Someone might want to add sashing to their quilt pattern for a few reasons. I’ll list the most common reasons you would like to use sashing on a quilt.

  • It adds length and width to your quilt.
  • It breaks up the quilt blocks, which you sometimes need depending on the block design.
  • It adds a nice frame around the quilt blocks.

How to Sew Sashing on a Quilt Block

There are a couple of ways to add sashing to a quilt block. You can use just sashing strips or a combination of sashing strips and cornerstone blocks. This tutorial will show you how to use sashing strips only to create a quilt with sashing. 

Step One: Calculate the Length and Width of the Sashing Strips

You should decide what width you want your sashing strips to be. Most sashing is between 1 ½” to 3” wide. It’s totally up to you what width you want to use. 

For this example, the illustrations will use 2” wide sashing. Don’t forget to add ½” for seam allowance. That means I need to cut my sashing strips 2 ½” wide. 

Next, measure the vertical edge of your quilt block. My example block is 9 ½” tall, so I need to cut my strips at 2 ½” x 9 ½”.

Step Two: Cut the Vertical Sashing Strips

I will be using 16- 9 ½” blocks for this example.

Each row needs five vertical sashing strips. I need to cut 20- 9 ½” x 2 ½” strips. 

Step Three: Add the Vertical Sashing Strips

Take the first block from the top row and sew a sashing strip on either side of the block using a ¼” seam allowance.

Step Four: Cut the Horizontal Sashing Strips

Measure the length of the rows. My example quilt measures 46 ½”. I will cut five 2 ½” x 46 ½” horizontal sashing strips.

Note: If you are cutting the horizontal strips from yardage and the length is longer than the WOF (width of fabric), you will need to sew two strips together to make a longer strip.

Step Five: Add the Horizontal Sashing Strips

Sew two horizontal strips to the top row.
