Piecing Instructions.
*Use a scant 1/4" on all seam allowances. See the Scant Rant series for details.

1. Make a Half-Square Triangle (HST) unit with Fabric A and Fabric B. Use (1) Fabric A square and the (1) Fabric B square to make (2) total Half-Square Triangle units using the method in this tutorial. The HSTs should be trimmed down to:
                     
12" blocks:  8 1/2" (unfinished size).
9" blocks:  6 1/2" (unfinished size).
**NOTE** The 2 large HSTs made in this step will be used for both blocks you make this month.  Each block requires only 1 of these HSTs.  I wanted to keep the same method of construction and reduce waste.

2. Make Half-Square Triangle (HST) units with Fabric A and Fabric C. Use the remaining (10) Fabric A squares and the (10) Fabric C squares to make (20) total Half-Square Triangle units using the method in this tutorial. The HSTs should be trimmed down to:

12" blocks:  2 1/2" (unfinished size).
9" blocks: 2" (unfinished size).

3. Layout the Half-Square Triangle Units as shown below.

4. Sew each of the four rows that surround the center A/B HST together, pressing seams in one direction.

5. Sew the rows on the left and right side to the large center half-square triangle.

6.  Sew the remaining rows to the top and bottom of the unit from step 5.

7. Make (2) blocks. They may be identical blocks or made from differing fabrics for a scrappier look.  As I pointed out in the note above in Step 1, to reduce waste, I used the same fabric for both the large center HSTs in these blocks.  Don't worry if you think they look too similar!  Once the blocks are separated on opposite sides of the quilt, it will be much harder to notice.
