An interesting block from perhaps the 1960s or '70s....
...Making two quilts in this pattern that I have photos of. I'm surprised
I don't have more. It's a cool design and very appropriate for the Fourth of July.
I'm guessing this is the repeat on the pink one.
It's hard to believe the design has no BlockBase number
and hasn't been published before 1970.
Here's the closest I've found and it's a recent pattern.
Lee Heinrich’s Turning Cartwheels
The vintage block is not easy to draw. I did this pattern in Electric Quilt and it's almost perfect. The four-sided colored shapes aren't exactly the same. Those on the diagonal (E) are slightly wider and longer than the others (F).
Cutting a 12" block
B - Cut 2 background squares 2-3/8". Cut into 2 triangles with one diagonal cut. You need 4.
C - Cut 2 background squares 4-3/8". Cut into 2 triangles with one diagonal cut. You need 4.
D - Cut a strip of background fabric 2" wide. Cut 4 diamond-like shapes at a 45 degree angle. Each should be 3-1/4" long.
F - Cut 4 scrappy strips 2" wide by 7-1/4" long. Cut the corners off at 45 degrees.
Rotate around to make a pinwheel.
I don't know the source on the vintage block but notice the
sashing. The pinwheel and the strips are all pieced of the same
If you love a puzzle try to figure out how to make that work. One size
shape in border and pinwheel.
Shade the diamonds yellow for an extra pinwheel
