The basic Pinwheel quilt block

A traditional Pinwheel quilt block patternTraditional Pinwheel quilt block design

The basic design is created when a half square triangle is repeated and rotated a quarter turn as you make your way around the block. 

There are several methods for making half square triangles.

Choose from the following lists based on your needs. (The number of half square triangles with the same fabric pairings is enclosed in parentheses.)

  • Triangle paper - (many, depends on the size of the HST, free to print from this website)

Finally, a paper pieced version of the Pinwheel quilt block is found here. It includes free downloads of the pattern in 2", 3", 4", 5", and 6" finished sizes, plus the cutting chart and a coloring/fabric planning page.

Something for almost any quilt you're working on.

Tutorials for all of these Pinwheel blocks are here on the website. Some form a pinwheel in the center, others have outside corners that rotate a 1/4 turn around a center square or unit. 

Regardless, they all have that twirly presence that adds movement to your quilt design.

Reminder to bookmark this page for updates

The finished sizes are listed below each one. If there is any paper piecing in the block, there'll be patterns to download for each of the different sizes. 

If you love Pinwheels, remember to bookmark this page. 

As new tutorials (and that includes any free paper piecing patterns or templates) are added, they'll be added both here and in the main Free Quilt Block Patterns library.

My favorite tool for trimming HSTs for Pinwheel blocks

The ideal ruler for checking the accuracy of and trimming half square triangles to size has the following characteristics:

A square ruler larger than the Pinwheel

I find it much easier to align a line on the ruler with a cut edge instead of trying to even up the cut edge with the edge of the ruler.

Much less eye strain, especially for these far-sighted eyes.

The second trim on an HSTIt's so much easier to align the lines on the ruler with the trimmed edges of the HST. The red arrows point to the 3-1/2" marks on the ruler, the unfinished size of HSTs for a 6" finished block.

Diagonal line (45°) from corner to corner

This line should be easy to see as you position directly over the seam allowance. With square rulers, this line is ALWAYS in the same place—right through the center diagonal.

Most rectangular rulers also have the 45° line. Many times, though, it isn't at the corner as in this Omnigrid 6" x 24" (red arrow).

A square rotary cutting ruler with a 45° lineThis 45° mark is useless for trimming HSTs.

Grippy bottom

If you've had problems with your ruler slipping a bit as you trim your HST, try a ruler with a grippy bottom.

I've used Quilters Select rulers, Creative Grids, and even my standard 6" square with a product called Grippy®; sprayed on the bottom or with Nexcare Tape stuck on the bottom.

For the longest time, the Quilters Select was my absolute favorite. But the 'grippy' stuff is coming off in the corners now (red arrow). The ruler has roughly 5 years of use, but I'm not seeing wear anything like this on my oldest Omnigrid rulers.

Creative Grids textured 'dots' on the bottom side of the ruler grab and hold the fabric nicely. Creative Grids ALSO has this texture in the seam allowances, too.

There's texture all the way to the edge to hold your fabric in place as you cut.

But what if you would rather not replace your rulers? They're expensive, right?

Grippy® saved my everyday square ruler (my bee-mates like it, too, when they tested it for me) by making the bottom grippy without being sticky or obscuring the markings.

It's all in the name, right?!!!

It can be a bit stinky, so do it outside. You won't accidentally get any gook spread about in your studio either. It dries fast, too.

And it can be reapplied if needed.

Finally, there's Nexcare Flexible Clear Tape. It can be applied to your older, still good, rulers. Add this to the underside of your ruler at the edges.

A square ruler with Nexcare tape applied to the top and bottom edgesThe Nexcare has a bit of texture to it, not as much as the Creative Grids texture. It's the milky bits about 1" down from the top and up from the bottom.

Any excess can be trimmed away with your rotary cutter. 

You might have expected me to say the Bloc Loc ruler. <heavy sigh> I wish I could because it's a foolproof way to line up the seam allowance of the center diagonal.

Unfortunately, I find that I've got to cut the corner twice. The fabric always seems to shift a bit there. Two extra cuts just isn't efficient for me. 

To address my problem, I've added strips of Nexcare Flexible Clear Tape to the trimming corners of my Bloc Loc. It helps.

Tips for making better, flatter Pinwheel quilt blocks

All quilters can agree that patches go together easiest when they're cut, stitched, and pressed accurately.

In my experience, starching your quilt fabrics before cutting makes all the different in the world.

The quilt fabric has less tendency to slip as you're cutting and stitching. If you use a 1/4" foot with a guide or flange on the right-hand side, the stiff starched fabric is easier to maneuver under the needle and up against the guide.

Starch fabric holds the crease from fingerpressing so much better than non-starched fabrics. By fingerpressing the seams, it much less likely that I'll get a tuck in the seam allowance.

Dealing with the bulk

At the center of a traditional Pinwheel, 8 seams meet. That adds up to a lot of bulk.

One of the best ways I've found to deal with this is to twirl or fan the seam allowance. You'll find this technique described in many of the tutorials on this site right where you need it in the instructions.

On the backside, a cute little pinwheel forms in the very center.

If you choose not to twirl the seam allowance, or you can't because you paper pieced, or if there aren't so many seams at the center, then check out this simple pressing trick for super flat blocks.

It's hard to believe that something as light as your rotary ruler can make such a big difference in the flatness of the finished block.

Pressing seams

Should your seams be pressed open—or closed and toward the darker fabric?

This really is a personal decision. I like to have seams that nest or abut to make matching them easier.

If you decide to press those seams open, you'll be pinning to hold the patches in place as you stitch.

Fine pins (my favorites are the IBC brand that are .50mm thick) a helpful, too, because they don't distort the fabric as much as thicker ones do.

A pinning tip...remember as you pin, to pin through the sew patches that are the front of the block and not through all the layers in the seam allowances.

Pin through just the patches and now the seam allowances

The units will feed through your sewing machine much flatter.

And finally, always stop right before you hit all the lumpiness at the center of the seam. Raise your presser foot, either manually or with a tap of your foot pedal depending on your sewing machine. Then lower the presser foot down on top of the lumpy part.

Raise your presser foot to set it down on top of the bulky center seamPin your unit so the edge of the seam feeds under your presser foot first. Stop just as you reach the bulk. Raise your presser foot and set it down on top of the bulk. Continue sewing. You'll get a better match at the center of your block.

Your sewing machine will have less tendency to push the lumpy parts forward. A better match is more likely.
