Half-Square Triangle Love

Half-square triangles have to be one of the most versatile quilting blocks around. HST’s are formed by cutting two squares in half diagonally from corner to corner, creating two triangles, and then sewing two different triangles together to make a square. There are many different ways to create these, but the outcome is one simple foundation block and that can be arranged in countless ways to create more complex blocks or layouts.

Let’s take a look at a few Bluprint patterns and projects that feature this basic block! The versatility of this block is always astounding.
