The Blocks and Pinwheels quilt block is chock-full of whirly-twirly goodness.
With nothing but half square triangles and cut squares, it's a dandy block to play with.
For our sample, the 8-at-a-time method for making half square triangles is a perfect match. Other than that the design contains nothing but cut squares.
Now if we could just jazz up the name a bit, eh?
Seams are all 1/4" and pressed toward the darker fabric unless otherwise noted.
Several common abbreviations are used in this tutorial:
When you press, do it first with the patch flat as it was sewn.
This sets the seam and helps meld the fibers of the thread with the fibers of the fabric together.
Then press your patches open from the front. This helps to avoid tucks pressed in at the seams.
Tucks are a pain in the derriere because they get in the way of your quilting—especially when you're trying to ditch quilt with your walking foot.

The 8-at-a-time method is used to make our HSTs. If you choose to make a quilt entirely from this block, you may wish to use another method to mass produce them.
Using the 8-at-a-time method for making HSTs, draw two diagonal lines on the back of either the #1 or #2 square. Choose whichever one is easier to see your markings on.
Install your favorite quarter inch foot, standard piecing stitch length.
With RST, layer #1 and #2, and stitch a quarter inch away from both sides of both lines.
Press the sewn units flat to set the seams.
From the chart below, find the 'Center/MidPoint Measurement' that corresponds with the Finished Block Size you chose. We use this to cut the #1/#2 patch into four equal squares.
|Trim HST to…
Find the Center/MidPoint Measurement on your ruler. Align that measurement on the ruler with the edge of your block.
For this 6" sample block, the Center/MidPoint is 2⅝" (white arrow).
Cut the patch in half from top to bottom through its center as shown below.
Rotate your mat a quarter turn and repeat.
You now have four units, each with two diagonal lines of stitching through them that are equal to the Mid Point Measurement.
Cut these units in half between the diagonal lines of stitching to form eight HST.
Return to the chart above, this time use the 'Trim HST to...' column. Trim to perfection!
This is what you've got when finished.
With RST, join a #1/#2 HST to a solid #3 square as shown below.
SA is pressed toward #3 to reduce bulk.
Set two of these two-patch units aside for Step 3.
For the two remaining, add a #4 corner square to both short sides.
Press, SA toward the center units.
Sew the four remaining HST into two pairs, pressing SA in the direction of the arrow. This is so that your seams will nest with the side unit you've already created.
With RST, stitch the two pairs together so that they form a pinwheel design.
For a good match in the center, I like to put a pin straight through the points on both sides. (Click here for more information about pin matching points.)
I then insert a pin on both sides of the pin already through the points (white arrow).
To finish up our center pinwheel, twirl the seam allowance in the center.
Do this by loosening the few stitches in the seam allowance—do not cut them away—and flatten the seams with your fingers. They will point clockwise around the center (as viewed from the backside).
Press into place.
Arrange the patches for your Blocks and Pinwheels as shown below.
With RST, join the sides to the center pinwheel block.
SA are pressed in the direction of the arrows.
With RST, stitch the rows together. Use pins to help you keep points that should match lined up.
This is your finished Blocks and Pinwheels quilt block. There's a lot of movement in this design for just a handful of HSTs whirling around a center!
And finally our Blocks and Pinwheels from the backside. You can see how the seams all nest around the pinwheel unit.
