Yet another Line Notes form but this is NOT a one page method.
When doing line notes AND being on book for a run thru I would inevitably fall into the trap: as I would stop to write a line note, someone would call for line and I wouldn't be able to respond quickly enough. So this is what I use...
Basically before rehearsal I cut the sheets at the divider lines which creates mini bookmarks of sorts. As I'm going along, if there is an error, I write the actor's initials on it, check what was done wrong (eg. paraphrased), use my shorthand to make a note in my script and leave the slip in my script where the error took place. Then, after the run thru while the director is giving acting notes, I go back thru and fill out the forms.
This works well for me with big casts (so I'm not shuffling thru sheets to find the right character), helps make them easier to read (my handwriting is clearer), and I'm able to focus on other things during the run (being onbook, tracking props, etc).
The downside is that actors can more readily see how many mistakes each other are making when they look at each others' stacks... However, I've also seen some more competitive actors use that as a bit of motivation to learn their dang lines!
The "mistakes" options are in an order that made sense to me - change it up to what makes sense to you.
