Double Pinwheel – Quilt Block Tutorial

Double Pinwheel

 Again, I'm sorry about the poor lighting. I'm still working on learning how to take decent pictures in the depths of the basement. It's my woman cave, really, there's no windows where I sew!

Step 1: Cutting the Fabric

Fabric A: Background fabric

• A1: four 3" squares
• A2: four 2 1/2" squares

Fabric B: Dark (blue)

• B1: two 3" squares
• B2: four 2 1/2" squares

Fabric C: Medium (grey dot)

• C: two 3" squares

Step 2: Sewing the Half-square Triangles

Draw a line through all four A1 background squares.
Pin each A1 square, right sides together, with the both B1 (blue) and both C (grey dot) squares.

Sew 1/4" on either side of the drawn line.

Cut along the drawn line.

Press open, and trim the half-square triangles to 2 1/2" using your favorite trimming ruler.
I like the Precision Trimmer 6" ruler.

Step 3: Sewing the Block Together

Set up your half-square triangles and your A2 (background 2 1/2" squares) and B2 (blue 2 1/2" squares) like the photo above.

Sew the rows together using a 1/4" seam.
Press the seams open.
Remember, this is my experiment quilt to see if I like pressing seams open.

Sew the columns together using a 1/4" seam. Press the seams open.

Hopefully you will have little or nothing to trim on your block. It should measure 8 1/2" square.
