This month's block is a mouthful! Half Rectangle Triangle blocks!  They are pretty easy blocks again. The main trick is to angle the background fabric in the right direction.

We’re going to make (3) different blocks using half rectangle triangles (HRT). These will be two double blocks, one oriented to the left and two oriented to the right, and one large one.  

This month you will need your background fabric and Colors 1, 2, and 4

Cutting for the HRTs: 

(1)  9” x 5” rectangle of Color 1.  

(1)  9” x 5” rectangle of Color 2. 

(1)  9” x 5” rectangle of Color 4.  

(3)  9” x 5” rectangles of the background fabric

(1)  17 1/2” x 9 1/2” rectangle of Color 4.  

(1)  17 1/2” x 9 1/2” rectangle of the background fabric

Step 1: Starting with our double HRT block in Color 4. 

Stack your background and Color 4 rectangles. Orient the fabrics with the Color 4 fabric straight and your background fabric angled as shown below, with right sides together. Mark the line from corner to corner. 

Step 2: Sew a ¼” seam on each side of your line. (This is a good spot to chain stitch again with the other rectangle blocks.)

Step 3: Cut along the line you drew in Step 1.

Step 4: Open the rectangles and iron the seam allowances open. Do this for both halves.

Step 5: Trim the blocks to 4 ½” x 8 ½” rectangles. 

Step 6:  Sew together the (2) HRTs with both HRTs oriented in the same direction as shown below. 

Step 7: Now for our other two double HRT blocks in Colors 1 and 2. 

Repeat steps 1-6 with your Colors 1 and 2 rectangles and the background fabric. For these blocks, orient your background fabric in the opposite direction of your previous block as shown below, right sides together. 

Step 8: Now you have three 8 ½” blocks! Two oriented towards the right and one oriented towards the left! 

Step 9: On to the large block! 

Orient the rectangles as you did in Step 7 and repeat Step 1. 

Step 10: For the oversized block you can choose to sew on one or both sides of your line. 

You only need one large HRT. You can sew on both sides for two HRTs and use one for the front and save one for the back of the quilt! Or, you can save your fabric and possibly use it in a future block. 

Then continue to repeat Steps 3 and 4 for this block. 

Step 11: Lastly, trim your oversized block to 8 ½” x 16 ½”  

And with that, we’re another 4 quilt blocks closer to a quilt top!!
