How to Create a Pinwheel Quilt Block

The name of this block is Pinwheel Quilt but I'm not sure why - there's no pinwheel in it! Learn an easy way to get those on-point four square patches to fit. It appeared in the Kansas City Star and is a variation of the Cross and Chains quilt block that also appeared in the Kansas City Star. I've also done a few layouts which you'll find at the end of the tutorial. Let's get sewing!

Fabric Requirements for a 12" Finished Pinwheel Quilt Block:

• Light/White: 2 - 5" squares, and 16 - 2.5" squares
• Medium: 2 - 5.5" squares
• Dark: 2 - 5.5" squares, 2 - 5" squares, and 1 - 4.5" squares (forgot to put that one in the picture!)

Sewing Directions:

Corner Units:

Step 1:

Using the Light/White 5" squares and Dark 5" squares, sew together four Half Square Triangle patches as shown in the picture below. Trim/square up the units to 4.5" square. You can find my tutorial for making Half Square Triangles at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-half-square-triangle-block

On-Point Four Patch Units:

Step 2:

Using the two Medium 5.5" squares and the two Dark 5.5" squares, piece together four Hourglass units like the ones shown in the picture below. Trim/square up the units to 4.5" square. You can find the basic Hourglass tutorial at https://fabric406.com/blogs/fabric406-blog/how-to-sew-a-basic-hourglass-or-quarter-square-triangle-block

Step 3:

Going from top to bottom, left to right, use the picture below for reference for these next steps:

• Mark a diagonal line from corner to corner on the back of two Light/White 2.5" squares. Then place on a Step 2 Hourglass unit and stitch along the marked line.
• Fold the Light/White 2.5" squares along the stitching, match the corners, and press
• Unfold the Light/White 2.5" squares and trim away the seam allowance
• Refold

Step 4:

Repeat Step 3 for a total of four units.

Step 5:

Repeat Step 3 with the other two corners of the Hourglass units as shown in the picture below.

• Mark a diagonal line from corner to corner on the back of two Light/White 2.5" squares. Then place on a Step 2 Hourglass unit and stitch along the marked line.
• Fold the Light/White 2.5" squares along the stitching, match the corners, and press
• Unfold the Light/White 2.5" squares and trim away the seam allowance
• Refold

Step 6:

Repeat Step 5 for a total of four On-Point Four Patch units as shown below.

Putting It All Together:

Step 7:

Lay out the Corner units, the On-Point Four Patch units, and the Dark 4.5" square as shown in the picture below. From here the Pinwheel Quilt block goes together like a basic Nine Patch block.

Step 8:

Now you can sew the units into three rows as shown in the picture below.

Step 9:

Next, press the seam allowances away from the On-Point Four Patch units as shown below.

Step 10:

Sew those three rows together and...

Step 11:

Press the seam allowances toward the center of the block. You're done!

Layout Options:

Here's a basic simple 4 x 4 layout. It always amazes me how different a block looks when sewn into a quilt.

In this example, I've simply added sashing and cornerstones so each individual block shines.

Next I substituted the On-Point Four Patch unit for the cornerstones. Of course I had to make the sashing bigger to accommodate the larger cornerstone.

Here's where I added a border using the On-Point Four Patch unit. It's a little busy for my taste but still looks nice.

Of course, I had to see what it looked like on point. Another great look!

Conclusion:

I really enjoyed sewing this block together. Once I figured out how to get those On-Point Four Patch units sewn without cutting odd-ball sized squares and triangles, it was fun! Doing these tutorials helps me up my game with sewing skills too! You do get a bit more fabric waste doing the unit the way I've shown in the tutorial, but I think it's worth it. Less stress about cutting and sewing small squares and getting them to fit into the 4.5" square parameter.
