I'm sorry this is so late.
This month we'll work on the Lady of the Lake Block.
It's made entirely of half-square triangles, which we've practiced several times in previous blocks.
The most important thing is to pay close attention to keeping the smaller HST units facing in the correct direction.
I've attached some directions.
Another source of directions for this version of the block can be found here:
