Half-square triangles, called HSTs, are a common unit in many quilt blocks. I have been creating lots of HSTs as I make the flying geese units in the Allietare quilt (Bonnie Hunter’s Winter Mystery 2015).
A seam along the hypotenuse/long edge will create HSTs, shown on the left below.
If you sew along a short edge, as pictured on the right above, you can make quarter-square triangles, which I put together in Broken Dishes units.
I have shoe boxes for the different types of triangles:
Someday I will make a scrappy quilt with these units. I really like the way Bonnie has used HSTs in Clue 5 of Allietare, so I am planning a scrappy version of this too.
In fact, Jeni Baker of In Color Order has written a whole book devoted to HSTs. Vicki Welsh of Field Trips in Fiber compiled many HST layouts as she was planning a project a while back. They are extremely versatile and you can create so many different looks!
What is your favorite HST block?
Happy Quilting from Andi
