12″ Finished Block: Double Friendship Star

From the 2026 Sew Flake Mystery Quilt Challenge

October Block One: Double Friendship Star

Instructions by Julie. Posted by Tia. (See PDF copy)

Julie’s Note: This block itself isn’t too difficult to assemble.

You will need 3 Fabrics, with an Optional Center that uses 2 Fabrics: Use the Coloring Diagram as needed.

Step 1 – Cut:

Background Fabric:
- Cut (2) 4 7/8” squares then Sub Cut on one diagonals
- Cut (4) 4 1/2” squares
Fabric One: Large Star Points
- Cut (2) 4 7/8” squares then Sub Cut on one diagonal
Fabric Two: Small Star Points
- Cut (4) 3 1/2” squares
Optional Fabric Three: Center Square Corners
- Cut (2) 2 7/8” squares then Sub Cut on one diagonal
Optional Accent Fabric: Center Square
- Cut (1) 3 3/8” square

Julie’s Note: If you wish to use only one fabric for the center square, eliminate the Optional Fabric Three and Optional Accent Fabric. Cut (1) 4 1/2” square in the color of your choice.

Step 2 – Mark: Mark all the 3 1/2” Fabric Two squares with a diagonal across the back. This should be done with a light pencil or a removable fabric type of marker. Frixion pens work well.

Step 3 – Make Large HST: Assemble the (4) Large HST blocks as shown in the diagram below. Set your seams and press.

Step 4 – Make Dual Point Squares: Using the Large HST Blocks from Step 3 and the 3 1/2” Fabric Two squares, place the Fabric Two squares on the corner of the Large HST Blocks as seen in the diagram below. Trim 1/4” from the drawn line. Set your seams and press. The finished Dual Point Squares should measure 4 1/2” square.

Julie’s Note: If you wish to use only one fabric for the center square, skip Steps 5 & 6. Use the (1) 4 1/2” square in the color of your choice in place of the Center Block.

Step 5 – Start Center Block: Start assembling the Center Block as shown in the diagram below. Set your seams and press.

Step 6 – Finish Center Block: Finish assembling the Center Block as shown in the diagram below. Set your seams and press. The Center Block should measure 4 1/2” square.

Step 7 – Arrange: Arrange (1) Center Block or Center Square, (4) Background Fabric Corner Squares, and (4) Dual Point Blocks as shown in the diagram. Sew together in order shown in the diagram.
