This simple 9 patch quilt block tutorial is written for the absolute beginner. You will see how to put a quilt block together.

The nine patch quilt block has many different variations - split nine patch, double nine patch, blooming nine patch. There are too many to count!

This quilt block is simply made up of nine squares, which can be any size. So, you can make a block in the size you want.

9 Patch Quilt Block Fabric Requirements

Any fabric will do, but done in contrasting fabrics the nine patch really shows up. You can cut the squares from strips that have been cut from yardage or scraps or use precuts.

In this tutorial I have designated the fabrics as follows

Fabric A = tone on tone solid (purple)

Fabric B = print (purple paisley)

Nine Patch Quilt Block Measurement Chart

Here are the cutting measurements for the nine patch quilt block in five sizes: 6 inch, 9 inch, 12 inch, 15 inch and 18 inch.

Choose your block size, cut your fabric accordingly and follow the instructions below to make the block.

Nine Patch Quilt Block Layout

Before sewing the block together, it helps to understand the underlying structure of the quilt block.The 9 patch block is laid out on a 3 x 3 grid: 3 rows and 3 columns.

Nine Patch Quilt Block Pattern layout

Nine patches make up the block. The patches can be solid squares or squares with multiple patches, as is the case for 9 patch block variations.

And, the patches from column to column can be unequal in size. However, the block itself is sewn together in the same way as shown below.

Nine Patch Quilt Block Pattern Instructions

  • Note: Refer to these instructions for stitching together most any quilt block that is laid out on a nine patch grid.

To show the sewing lines I have used a contrasting red thread. You would use thread that matches, or blends with, your fabric color.

Step 1 Choose Block Size and Cut Fabric: According to the block size measurement chart above, from Fabric A cut 5 squares, from Fabric B cut 4 squares.

How to Sew a Quilt Block Together

Step 2a Stitch Row 1 Together: Near your sewing machine layout the block in the grid format as pictured above in the block layout. Taking each row in turn, and without changing the orientation of the patches (squares), stitch the patches in each row together.

Row 1: Place the square from column 2 right side down on top of the square in column 1.

Step 5 Press Seams of Each Row with Iron: Take the sewn rows to the ironing board and press this seams with an iron in the direction that they were finger pressed. For flatter seams, use a starch alternative pressing solution if desired.

See below how the seams of each row is pressed in opposite directions. This is so that you can reduce bulk by nesting the seams when you sew the rows together.

How to Square Up a Quilt Block

Step 8 Square Up Quilt Block: Trim the block to size. When squaring up a quilt block, trim it to size based on the unfinished size of the block.

I have a 9 1/2 inch unfinished block. To trim it, I place the 5 1/4 inch vertical and horizontal measurement lines of the quilting ruler in the center of the block and cut off a little excess fabric. I simply eyeballed the center of the block.

Nine Patch Quilt Block Pattern Step 8a

If your block is just short of being the size you were aiming for simply trim them all to the same size. Due to variations in cutting and stitching sometimes your completed block may not end up being the exact size you wanted to be. But it should be very close.

You can also square up the quilt block based on the original unfinished patch size. In this case the right and left columns of the block should measure 3 1/4 inches (1/4 inch of each is used in the seam allowance). The center column should measure 3 inches in width but it is not of concern at the moment.

  1. Place the 3 1/4 inch measurement line of the quilting ruler along the seam of the right column and trim.
  2. Turn the block a quarter turn clockwise and repeat.
  3. Repeat Steps 1 and 2 for the other two sides.
