Sewing Directions:

Half Square Triangles:

Step 1:

Using the Light/Ivory 5" squares and Medium/Tan 5" squares, sew together four Half Square Triangle units as shown in the picture below. You can find my step-by-step method for making a Half Square Triangle block at

Green Diagonal Stripe Units:

Step 2:

We'll basically be making a modified Flying Geese unit - the position of the squares is the only difference. Draw a diagonal line from corner to corner on the back of a Dark/Pink 2.5" square and a Dark/Brown 2.5" square. Match these up with a Medium/Green 2.5" x 4.5" rectangle as shown below.

Step 3:

  • Sew the Dark/Brown square to the Medium/Green rectangle along the marked line (top left image). Be sure to have the same orientation as in the picture.
  • Then do the same with the Dark/Pink square on the opposite corner of the Medium/Green rectangle (top right image).
  • Match up the corners of the squares and press (bottom left image).
  • Trim away the excess seam allowances (bottom right image).

Step 4:

Repeat Steps 2 and 3 for a total of four Green Diagonal Stripe units.

Light/Print Diagonal Stripe Units:

Step 5:

Using the remaining Dark/Pink 2.5" squares and Dark/Brown 2.5" squares, along with the Light/Print 2.5" x 4.5" rectangles, repeat Steps 2 through 4 to make four Light/Print Diagonal Stripe units. However, the orientation of the diagonal stripe is going in the opposite direction. Use the picture below for a reference.

Chevron Units:

Step 6:

Match up one Step 4 and one Step 5 unit as shown in the picture below.

Step 7:

Putting It All Together:

Step 9:

Now you can lay out the Half Square Triangle units, the Chevron units, and the Dark/Brown 4.5" square as shown in the picture below. From here the block goes together like a typical Nine Patch block.

This Starshadow block was fun to put together. It takes six different colors so you could get a bunch of different looks by changing out the lights and darks. I bet it would look great using different values of one color too - like six different blues.
