Pinwheel Block of the Month Series

Assembling Pinwheel Block #12
BOM #12 - the last in the series

Above: The outline for this blocks shows that you could
use 4 half square triangles (HSTs) and 12 squares for the
most direct assembly. But this requires a lot of cutting.
For a finished size 8" block each square will be 2.5" unsewn.
For a 12" finished size block, each square will be 3.5 inches.

Above: Instead you might want to cut the center portion as
one larger square instead of sewing 4 small squares together.
Remember, you'll need to have a 1/2 inch seam allowance.
So if you are making an 8" block this center square will be
4.5 inches. For a 12" block this center will be 6.5 inches.


Next make and attach two pairs of one HST and one square to
each side of the center square.

If you need help in quick ways to make HSTs - see the article here about
various methods: HST Article HERE
See the top square above to remind you of sizes.


Above: The last step is to make the top and bottom set
of 3 squares and one HST and attach. You may wish
to cut the two squares as a one unit rectangle?
If so an 8" finished block would have rectangles cut 2.5 x 4.5 inches.
A 12" block would have the 2 rectangles cut to 3.5" x 6.5"

Above: Your finished block will look like this.

Remember: once you have made 1-2 practice blocks, be sure to
think about how you can cut and sew several units at a time in
a chain piecing method rather than continue to make each block
completely separately.
