Those look great, Katybob! You don't have to cut any blocks in half. Certain ones can be opened up on the seam to form the two half triangles, and they will have the seam allowance so they fit. Some of us deliberately did not join that center seam in the blocks that can be divided diagonally.
The ones that can divide that way are (in order):
Charlotte
Granny
Jenny
Jewel
May
Mrs. Taft
Ruby
Sara
There are a couple of others that could be split diagonally, too. Any block who's final seam is the full diagonal, just undo that seam. No cutting.
