This Irish Chain block is based on the nine patch block that we are all familiar with. When you search for this block on the web you will find that there are quite a few variations of this block out there.

I was wanting a block for my group that would go with the St Patrick's day theme. When I became the BOM coordinator for my group I spent a few weeks creating a few simple BOMs to use as the year progressed. This was one of the very first blocks I created and that was before I bought the EQ7 quilting software!

If you saw my first BOM here for this block then I apologize and I have now updated the images and instructions!

The table below gives you the cutting directions to make this block - seam allowances are included.





6 1/2" x 2 1/2"

White Rectangles


2 1/2" x 2 1/2"

White squares


2 1/2" x 2 1/2"

Green Squares

Sewing Instructions:

  1. Make up the nine patch block in the center
  2. Sew one white rectangle on each side (left and right) of the nine patch
  3. Sew a green square either end of the 2 remaining white rectangles
  4. Sew these to the top and bottom of the block

Wasn't that an easy block to construct.

Once made there are so many ways to use this block to create a quilt top. It works well on its own or combined with sashing. Another option is to combine it with other blocks often called alternate blocks or simple blocks. Below I have listed a few of these.

  • Double Irish Chain
  • Snowball
  • Puss in the Corner
  • Half Square Triangle
  • Four Cross
  • Plain Block - a single square of fabric the same size as the original block.

Some people like to ensure that all the blocks within their quilt are of similar dimensions so that all the seams match - so this is good to think about when deciding which block to use with any other block in the same quilt.
