Now working counterclockwise, I attached the top triangle and then pressed.
Then the third triangle was sewn onto the right side of square and pressed.
And lastly, the bottom triangle. (Note that this is a different block that I used for this photo so the fabrics/colors are arranged differently.)
I then pressed again and cut off all the tips.
Blocks were then sewn together to form rows, and rows were sewn together.
Well almost, I'm still working on sewing the rows together.
