Mystery Quilt 2020 – Block 9
Updated: Jun 23, 2021
Welcome back and I hope you’re ready for a weekend of stitching!
I am looking forward to some free time this weekend to catch up on my blocks, and be ready to show you my quilt in just a couple days!
Great news, we were able to get a few more Super Bloom fat eighth bundles. If you need a bit more fabric or maybe just a splash of Super Bloom, these are perfect for you.
On to our next block!
For Block 9, you will need: (choose the fabrics shown above from your Super Bloom bundle)
1/2 yard blue fabric
1/2 yard light fabric
We will be making 16 blocks. The cutting directions are listed below:
64 blue half-square triangles cut from 32 squares 3-7/8″
64 light half-square triangles cut from 32 squares 3-7/8″
Start by making blue half square triangle (HST) unit, join one 3-7/8″ light half-square triangle and one 3-7/8″ blue half-square triangle.
Chain sewing works great when we have a lot of triangle units to make!
32 HST units need seam allowance pushed toward light and 32 HST units need seam allowance pushed toward blue fabric.
Keep these groups separate, this is an important step in preparing for assembly.
Trim all HST units to 3-1/2″ x 3-1/2″ using your ruler.
Select 4 triangles – 2 with seam allowance toward light, and 2 with seam allowance toward blue. Alternate seam allowances when arranging HST units into block shown above.

Sew into rows.
Push seam allowances in opposite direction as shown above.
Pin and sew rows together.
Square your blocks to 6-1/2″. I use my 6-1/2″ Creative Grids ruler and OLFA Spinning Mat to trim these blocks.
Repeat until you have completed 16 Mystery Quilt Block 9s.
Our ninth blocks will be positioned as shown above in our Mystery quilt!
