The last
block pattern I shared for the Block of the Month Club had several half square triangles (HST) in them. I used the HSTs that were bonus squares from the
Flying Geese block.
I thought I would share a quick tutorial on how to make HSTs if you didn't have the bonus squares or if you would just like to know how to make them on your own.
In this Half Square Triangle tutorial, you will use 2 squares of fabric which will give you 2 half square triangle blocks.
