Half-Square Triangle Block of the Month December Quilt Block 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.

Happy December! (a day early, hehe) Today I'm sharing with you the LAST block of our block of the month series! Can you believe it? I hope you've enjoyed this series! I'll be sharing finishing instructions later in December. Let's tackle this final block.

Traditional Method:
- (8) 4" squares from background fabric (white)
- (2) 4" squares from print fabric (yellow)
- (2) 4" squares from second print fabric (green)
- (2) 4" squares from third print fabric (turquoise)
- (2) 4" squares from fourth print fabric (navy)

Alternative Method:
- (4) 6" squares from background fabric (white)
- (1) 6" squares from print fabric (yellow)
- (1) 6" squares from second print fabric (green)
- (1) 6" squares from third print fabric (turquoise)
- (1) 6" squares from fourth print fabric (navy)

1. Assemble your half-square triangles using either the traditional method, or the alternative method. Press seams open.

2. Trim your HSTs to 3.5" square.

3. Arrange your HSTs as shown in the image above.

4. Sew your HSTs into four rows. Press seams in alternating directions.

5. Sew your four rows together, pinning where the seams match up. Press seams open. Trim block to 12.5" if necessary.

Voila! You're done! :)

If you create a block using this tutorial I hope you'll add it to the flickr group!

Happy Sewing!
