Half-Square Triangle Block of the Month Quilt Tutorial - In Color Order
Welcome to the Half-Square Triangle Block of the Month! For each month in 2012, I'll present a quick tutorial for a traditional quilt block using half-square triangles (HST)! Feel free to join in at any time! For past posts see here.

Yay! It's finally time for the reveal of our Half-Square Triangle Block of the Month Quilt! It's been a fun year, let's wrap this puppy up!

Finishing Instructions
You may of course choose to put your blocks together however you like! I'm provided instructions here to construct your quilt like mine.  It features sashing with cornerstones and large borders to give it a bit more size.  I choose to quilt mine with my signature free-motion loops! It has now been washed and it's crinkly soft goodness enjoyed! Now, let's finish your quilts!

- 2/3 yard of sashing fabric
- Print scraps from your blocks
- 1 yard of border fabric
- 3.5 yards of backing fabric
- 62”x75” piece of batting
- 1/2 yard of binding fabric

Seam Allowances: 1/4" unless noted
Finished Size: 54"x67"

From sashing fabric:
- Cut 11 strips, 2” x WOF
- Subcut strips into 31 rectangles 2”x12.5”

From print fabric scraps:
- Cut 20 squares 2”x2”

From border fabric:
- Cut 6 strips, 6” x WOF
- Subcut 2 strips into rectangles 6”x25.5” (2 total)
- Trim remaining strips into 6”x42” rectangles

1. Press all your completed blocks and trim to 12.5" if needed.

2. Lay your blocks out using the diagram above. There is a blank worksheet here (also seen below) that you can download and fill in with your own unique layout.  You’ll have four rows of three blocks each.

3. Sew a 2”x12.5” solid sashing piece to the left side of each block.  Press seams towards the sashing.

4. Sew your blocks together in each row, making sure there is a sashing strip between each block. Add an additional 2”x12.5” solid sashing piece to the end of each row. Press seams towards sashing.

5. Construct your horizontal sashing pieces by sewing a 2” print square to one end of each remaining 2”x12.5” solid piece. Press seams towards solid.

6. Sew these pieces together into five strips, each strip containing three solid pieces and four squares. Press seams towards solid.

7. Sew your rows together with a row of blocks between each pieced sashing strip. Press seams open.

8. Now it’s time to add the borders. Take two 6”x42” pieces and sew them to the top and bottom of your pieced top.  Press seams open.

9. Take two 6”x42” pieces and sew two 6”x25.5” pieces to the end of each one. Press seams open.  Strips should measure 6”x67”. Sew these two strips to either side of your quilt top. Press.

10. To make your backing, cut your yardage in half. Press. Trim off the selvedges and sew your pieces together lengthwise. Press seam open.

11. Baste (tutorial), quilt, and bind (tutorial) as desired. Binding yardage listed is for 2.5" strips, you'll need six.

Voila! You're done! I hope you'll be posting your blocks, finished quilts and projects made from this series in the In Color Order Flickr Group!

These tutorials will all remain available on the blog, they'll simply move to the tutorials page after the first of the year! I've turned all of the information from our series, including both half-square triangle construction methods, all twelve blocks, and finishing instructions into a PDF pattern, for those that prefer having everything in one place! You can find the Half-Square Triangle Sampler Quilt pattern here.
