That would put the outside pieces on the biase and you wouldn't want that.
To get the corner triangles, you would take you finish size and add 7/8" and then cut corner to corner and get two half square triangles. I don't do 7/8...I add at least 1" to mine,
Sorry, I was wrong about that.
This is what quiltville has.
