Mystery Quilt 2020 – Block 11

Updated: Jun 24

Welcome back! I hope you had a relaxing weekend and are ready to jump back into quilting!

Your stack of blocks should really be growing now! I am so proud of everyone. I absolutely love seeing your pictures and the incredible progress you’ve made!

Let’s get to it!

This block has a few extra pieces and it can be easy to get confused. Please follow along and watch the layout of the block!

For block 11, you will need: (choose the fabrics shown above from your Super Bloom bundle)

  1. 12″ light square

  2. 10″ dark blue square

  3. 10″ light square

  4. 10″ light square

  5. Fat eighth dark blue fabric

We will be making 4 blocks. The cutting directions are listed below:

  1. 4 light half-square triangles cut from 2 squares 2-3/8″

  2. 4 dark blue half-square triangles cut from 2 squares 2-3/8″

  3. 16 light half-square triangles cut from 8 squares 2-3/8″

  4. 12 dark blue half-square triangles cut from 6 squares 3-7/8″

  5. 4 light half-square triangles cut from 2 squares 3-7/8″

  6. 4 – 2″ x 2″ dark blue squares

  7. 4 – 3-1/2″ x 3-1/2″ light squares

It is important to do just one section at a time of this block. Let’s start with the unit shown above.

Start by making a dark blue half square triangle (HST) unit, join one 2-3/8″ light half-square triangle and one 2-3/8″ dark blue half-square triangle as shown above.

Press seam allowance toward the dark blue and trim the HST unit to 2″. I use my Creative Grids 4-1/2″ ruler.

Next sew two light 2-3/8″ HST to the initial unit. Press seams toward light.

Finally add dark blue 3-7/8″ HST as shown above.

Press seam toward dark blue and trim this unit to 3-1/2″ x 3-1/2″.

For the next unit, we will begin by arranging the dark 2″ square, two light 2-3/8″ HST, and 1 dark blue 3-7/8″ HST.

Start by sewing the two small light triangles to the dark blue square.

Push seam allowance toward the light triangles, then add the dark blue 3-7/8″ HST as shown above.

Press seam allowance toward dark blue and trim this unit to 3-1/2″ x 3-1/2″.

Arrange and sew 1 light 3-7/8″ HST and 1 dark blue 3-7/8″ HST.

Press seam allowance toward the blue and trim to 3-1/2″ x 3-1/2″.

Arrange all 3 units and 1 light 3-1/2″ x 3-1/2″ square as shown above.

Sew to rows, then sew rows together. Press and trim to 6-1/2″ x 6-1/2″ using your Creative Grids 6-1/2″ ruler. If you feel you need additional help, click here to see Block 11 video on our YouTube Channel.

Our eleventh blocks will be positioned as shown above in our Mystery Quilt! Notice the rotation of this block around the quilt.

I can’t wait to show you what’s coming next!

Are you already looking for inspiration for the next project? We’re all in this together and the “Made in USA” quilt might be just perfect.
