How to Make a Single Irish Chain Quilt Block Pattern

Easy Quilt Block

An easy and simple block to make. If you are a beginner quilter, you can make this block.

It’s one of the classic nine-patch blocks that have beautiful results on a quilt top. It may seem like a plain block; however, when they are connected, they seamlessly link to each other and create diagonals or an on-point layout throughout the project.

You can sew the fabric together one piece at a time for the square. However, I learned from Janet Wickell on The Spruce, that you can use a strip piece method for making multiple blocks quickly.

Single Chain or Double Irish Chain Block

The directions and sizes for today are for what I have been calling the single Irish chain. However, in my quilting software and several patterns, this is referred to as the Double Irish Chain. Either way, here is the tutorial. I have a photo of the referenced quilt block for you so you can determine if this is the square you want to make.

Fabric Considerations

Use a contrasting background fabric to help the design stand out. Both print and solid fabric work well for this.

Pattern Notes

Sew fabrics together using ¼” seam allowances.

Sew fabric with the right sides together.

Fabric can be sewn together one piece at a time. However, If you need to make more than one block, assembly is faster when the quilt block is strip pieced from fabric strips sewn together, then cut apart. And sewn back together as shown in the chart.

Today, my square uses a solid quilt center. However, you can change this up and make a 9-patch center using a variety of fabrics.

With the right sides together, sew the darker fabric “A” strip lengthwise to the wider lighter fabric “A” strip. Repeat this process and add the second darker fabric strip on the other side.

Press the seams to the outside towards the dark strips.

Using a quilting ruler and rotary cutter, square up one end of the long strip. Then cut into segments using the following measurements, as shown in the diagram.

  • 1 11/16″ long for the 6” block.
  • 2 1/8″ long for the 8” block.
  • 2 1/2″ long for the 10” block.
  • 2 7/8” long for the 12” block.

Press the seams to the inside towards the dark strips.

Using a quilting ruler and rotary cutter, square up one end of the long strip. Then cut into segments using the following measurements, as shown in the diagram.

  • 7 11/16″ long for the 12” block.

Assembling and Sewing the Single Irish Chain Quilt Block

With the right sides together and using ¼” inch seam allowance, sew an “A” section onto the top of a “B” section. Make sure to nest seams. Press the seam allowance toward the “B” section.

Sew another “A” section onto the bottom of a “B” section. Nesting the seams and using ¼ inch seam allowance. Press the seams towards the “B” section.

Trim the quilt block ½” inch taller and wider than the desired finished size.

Continue repeating this process until all your blocks are sewn together.

If you just have one block to make or prefer not to use the strip piecing method, here are the directions for making just one block.

I will be using the 10” block as an example; however, use the sizes noted above when making a different size block.

Fabric Requirements

For the darker fabric, cut four little squares 2 ½” X 2 ½” and one square 6 ½” X 6 ½”.

Using the Lighter fabric, cut four rectangles 2 ½” X 6 ½”.

Begin by placing a 2 ½” X 6 ½” lighter rectangle on the left and right side of the darker fabric 6 ½” X 6 ½” square.

With right sides together and using ¼” seam allowance sew the rectangles to the left and right of the darker center square. Press seams to the darker fabric.

Next, you’ll be sewing the smaller squares onto the rectangles.

Layout the two remaining light fabric 2 ½” X 6 ½” rectangles. Place a 2 ½” X 2 ½” dark fabric square on the left and right end of each rectangle.

With right sides together and using ¼” seam allowance sew the squares to the left and right of the lighter rectangle. Press seams out to the darker fabric.

Assemble the Square

You now have three rows of fabric strips to sew together that match the Sections “A” and “B” described above.

With the right sides together and using ¼” inch seam allowance, sew an “A” section onto the top of a “B” section. Make sure to nest seams. Press the seam allowance toward the “B” section.

Sew another “A” section onto the bottom of a “B” section. Nesting the seams and using ¼ inch seam allowance. Press the seams towards the “B” section.

Trim the quilt block ½” inch taller and wider than the desired finished size.

Continue repeating this process until all your blocks are sewn together.
