Tips And Tricks For Constructing The Pinwheel Quilt Block:

Make your quilting easier by using the right tools for the job

Cutting Instructions For The Pinwheel quilt block✂️

Color A (Blue):       1 - 7.5" Square
Color B (Red):        1 - 7.5" Square
Color C (White):      2 - 7.5" Squares

Let’s Piece the block!

4 squares of fabric cut for quilt piecing

The First Step Is To cut the squares to be used in constructing our Pinwheels

  • 1 Blue (Color A) 7.5″ Block
  • 1 Red (Color B) 7.5″ Block
  • 2 White (Background Fabric) 7.5″ Blocks

We are constructing two at a time half square triangles, so pair each color with its own background square to begin.

half square triangles cut apart and ready to be pressed

Sew and construct the HST units. Cut them apart.

Sewing stitch lines on two blocks and cutting them apart provides the 4 blocks needed to make the final Pinwheel. They are sewn, cut apart, and ready for pressing and trimming.

Once the blocks are pressed, square them to 6.5″. Each HST will need to be trimmed down to a finished size of 6.5″

Lay the HSTs into their finished position.

A pinwheel is nothing more that a fancy 4 patch! It’s a 4 patch where each block is a half square triangle. Lay your blocks as you want them to appear and construct your final block like any other 4 patch. Sew them first along the north/south midlines to create 2 units and then sew those two together along the central east/west midline.

The final Pinwheel Quilt Block

After last week’s Diamond block with all of its intersections and pickiness, I thought having something fun and fast was appropriate! A Pinwheel is another classic quilt block, which is why I like it so much. You know I love a good classic sewn in modern fabrics.

I used my main project colors in this block along with the background fabric. I selected red and blue as my primary colors and then used yellow as an accent color. I love the patriotic feel of these colors together and a series of four of these would make a fantastic wall hanging or table runner.

You can pick any two colors or prints YOU like best, and then pair them with a neutral background fabric for a design that POPS!


Joining in with us on the Power of 3 Row Quilt?

If you are making the full row quilt you’ll need the cutting instructions for the full row which appear below.

Color A (Blue):       4 - 7.5" Squares
Color B (Red):        4 - 7.5" Squares
Color C (Yellow):     8 - 7.5" Squares

You also need instructions for the other blocks:

Remember that in quilting, your wrong side is just as important as the front side.

Carefully press your seams to give the flattest block possible. Since this block is in essence a four patch, nesting your seams for the top and bottom halves of the block work beautifully. I then pressed the center horizontal seam open to give me the flattest possible result.



Thanks for stopping by today! I hope you’ll piece your own Power of 3 Row Quilt where we explore the power of using 3 strong colors to create a cohesive color story for our quilt. Here is the illustration of the Patriot’s Heart Quilt block to help you see the construction.

How to follow along with the Power of 3 Row quilt:

  • I’ve designed this quilt around publishing a new block once a week. So you will see the instructions to construct each new block once a week. I’ll share the instructions to make one block as well as all 4 if you wish to construct a full row each week. I recommend making a full row each week and at the end of the 5th week, you have all the rows completed and joined.
