Method for making 2-point grid

Class, here's a webpage from the online ILL625 that shows the procedure for making a 2-point grid.

This is part of next week's lesson. Please let me know if you cannot see this.

Here's the same treatment of the one-point grid instructions. (I'd already posted these here as separate images--that clunkiness has now been removed!)

This is coming off a slow server, so it will take a few extra seconds.
